This PR adds a hierarchy index to our suggestion database. The index will be used in the future when building documentation pages. E.g., documentation of the Module includes all the Types defined in this module; documentation of the Type includes documentation for every Method and Constructor defined for this type.
We could call this index "self-type index", but the Type-Module relation is not using self-type.
No visual changes to the IDE were made.
# Important Notes
We rely on the order of updates from the engine. In particular, the following scenario would lead to inconsistency in the DB:
1. Engine sends an update, changing the parent module of some type to "NonExistentModule"
2. Engine sends an update, adding a new entry "NonExistentModule"
I assume that the engine would never send the update with a non-existent qualified name used.
This PR provides a visual indication of whether the project's current state differs from the most recent snapshot saved in the VCS. The project name displayed in the IDE changes to a darker text to indicate that the VCS snapshot is outdated, and back to a lighter text when the current project state corresponds to the last saved VCS snapshot.

The outdated project snapshot indicator is set when:
* A node is moved.
* A node is added or removed.
* The text editor is used to edit the text.
* The project is auto-saved, and the auto-saved project state does not correspond to the last saved snapshot in the VCS.
The outdated project snapshot indicator is cleared when:
* A new project snapshot is successfully saved using `ctrl+s`.
* The project is auto-saved, and the auto-saved project state is confirmed to correspond to the last saved snapshot in the VCS. This occurs, for example, when a project change is undone and the project is reverted to the last saved snapshot state.
The auto-save events do not occur immediately after a project change but have a short delay, thus the VCS status update is affected by the same delay when triggered by an auto-save event.
Currently on every keystroke we try to refresh the Component Browser content. Due to some performance problems one refresh can take > 500 ms, so several keystrokes can hang our app for few seconts.
This PR mitigates this problem by refreshing the CB only when 200 ms passes since last keystroke. It should not be problematic for the user (actually many search engines, like this in IntelliJ do this), but we avoid choking our app with multiple CB refreshes at once.
Fixes the regression when IDE fails to create a project from template. Project name should start with an upper case letter to pass the server side validation.
This PR is a draft PR while I learn EnsoGL. The eventual goal is to implement the projects list portion of the cloud dashboard in this PR. This PR will implement part of https://www.pivotaltracker.com/n/projects/2539513/stories/183557950
### Important Notes
This PR is still really rough and contains a lot of hacks & hard-coded values. The FRP usage is also likely to be suboptimal and need fixing.
Save a snapshot of the project directory to the VCS on `ctrl+s`. If the operation fails because the VCS was not initialized previously, it will try to initialize the VCS first and then save a snapshot.
This PR fixes the `code_to_insert` method of entry to insert valid code according to the newest language version. Also created a separate method for getting imports required by given entry.
Now, method entries do not add imports (except when they are extensions), and are insterted with place for this type `_.method`. Static methods and constructors are inserted with the type name, and proper import for type is added.
There are some additional work done:
* The ReferentName and NormalizedName were removed, as we are now case-sensitive.
* All QualifiedName structures were replaced with new one in `name` module, as there is no longer functional difference between type qualified name and module qualified name.
* The QualifiedName structure removes "Main" module segment where it is not necessary, thus simplifying our code base and avoiding potential issues.
* Added macro `mock_suggestion_database` which should make creating consistent mocks of SuggestionDatabase much simpler.
* Fixed bug where the visualization preview show no value for some time.

# Important Notes
The tests in controller/searcher.rs file are not of the best quality, but those will be overhauled anyway when implementing my next task.
This is a part 1 of the fix for https://discordapp.com/channels/401396655599124480/1041669067188219914/1041669067188219914
Every time the node would have a connection going into a lambda body, the entire lambda in the destination node was replaced with the input variable. That because the lambda for some reason is not decomposed into span tree, and the presenter created a connection going to the port spanned over the entire lambda, and then thought this was a connection created by the user.
Such connections, going into "inside" of the span tree, should not break nodes expression, so they are not displayed at all after this fix. The proper fix will be making span-tree lambda decomposition, but it will be a next PR.
Fixes regression about inaccessible node output port. https://www.pivotaltracker.com/n/projects/2539304/stories/183792368
Additionally, a related issue related to nodes not being visible after initial load has been uncovered and fixed in the process.
# Important Notes
Previously the output shape size was only updated when node size itself was updated. When node's expression was changed, the output port view is recreated from scratch, but the current node size has not been propagated to the newly created port. In some cases the node size was changed shortly after, masking the bug. In other cases, the newly created shape size was never set.
The port size management has been moved from model method into frp network, and the initial size value is emitted during network initialization.
Fixes [#183511669](https://www.pivotaltracker.com/story/show/183511669)
This PR improves the `ImportInfo` structure from Double Representation crate so it provides information what names are brought into the scope with this import. The from_ast method also recognized [various ways of defining imports](https://github.com/enso-org/enso/blob/develop/docs/syntax/imports.md)
# Important Notes
The parser seems to not recognize properly imports with aliases. I have not fixed that, as we expect a new parser to be merged very soon.

This PR fixes an IDE freeze introduced by https://github.com/enso-org/enso/pull/3732 and reimplements reverting edited nodes to their previous state.
The cause of the IDE freeze is quite interesting. A detailed investigation is available [here](https://gist.github.com/vitvakatu/785e34881368b8cfda61715d7543cbd0).
The graph editor needs to update the Presenter state only if the user is editing the node. Before this PR, the graph editor notified the Presenter with a visual representation of the node content instead of code expression. It caused inconsistency between the states of the controller and Presenter and caused severe performance issues.

# Important Notes
- ~~There is a more complex alternative solution – it requires refactoring of the `component::node::input::area` module. The Presenter can be notified with `expression.code` changes, not `expression.viz_code`. I found a simpler solution (`.gate(&edit_mode)`), which has the same effect but does not require additional refactoring.~~ Said solution is implemented in a separate commit
When hovering the mouse pointer over the Marketplace button on the left bar of the Component Browser, show a caption informing that the Marketplace will be available soon.
https://www.pivotaltracker.com/story/show/182613789
#### Visuals
The video below demonstrates the caption shown when hovering the Marketplace button on the left bar of the Component Browser. It shows the caption disappearing after a hardcoded time, or when the mouse pointer is moved away from the button.

# Important Notes
- The "Label" visual component was fixed. Previously, the width calculation of the background was not synchronized correctly with the text width. As a result, a zero-width background was displayed when a Label was shown for the first time.
This PR implements displaying a currently active section name as a first crumb in the breadcrumbs panel. Sections are called `Popular`, `Modules` and `Local`.
https://user-images.githubusercontent.com/6566674/194551276-90bd7d6b-8509-43ec-b3c0-11c35fda9063.mp4
# Important Notes
This PR also contains a fix for [this bug](https://www.pivotaltracker.com/story/show/183499312). It was caused by mistake in the FRP implementation of the breadcrumbs. You could only trigger this bug after code changes in the `animation/loop.rs` module. It is not possible to see it otherwise. Still, the code was not correct, and now it is fixed.
This PR introduced an overhauled Component List Panel implementation, making use of the efficient EnsoGL grid view component. Also, it delivers a couple of new features:
* A part of the new design: there are no more section headers in grid, instead groups are "glued" together. The local scope section is under "popular" (old "favorites").
* The keyboard management inside grid works.
* there is a mouse hover highlight
* selecting the lowest entry in section when jumping with navigation bar.
* accepting input as-is with cmd/ctrl + Enter.

### Important Notes
**What is not implemented:**
* [Focus management between panels.](https://www.pivotaltracker.com/story/show/180872763) The grid is always focused. To accept the current input, use ctrl+Enter shortcut.
* [Proper handling of selection when having empty space on the right and pressing right arrow.](https://www.pivotaltracker.com/story/show/183487880)
* When entering a module, its name is not added to the input as described in the design doc. Will be a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
**Known issues**
* [the selection, especially in the local scope section, has sometimes an undesirable offset](https://www.pivotaltracker.com/story/show/183487730). The cause is known, but not so easy to fix.
* The inserted nodes are often producing errors. The Browser's inherits the outdated understanding of the language from old Node Searcher, and it does not include new form of imports, static methods etc. Those all will be fixed as a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
* The performance is improved, but still not ideal, due to problems in [text areas](https://www.pivotaltracker.com/story/show/183406745).
* To scroll the documentation panel, you must first click on it.
There was a regression introduced by PR #3678 with text synchronization between IDE and the Engine. This PR fixes it.
It was reproducible as an error log about version mismatch in a case when the metadata becomes shorter (e.g. on removing node).
