[The Task](https://www.pivotaltracker.com/story/show/180887253)
A new (+) button on the left-bottom corner appeared. It may be clicked to open searcher in the middle of the scene, as an alternative to tab key.

# Important Notes
* The window_control_buttons::common was extracted to separate crate `ensogl-component-button` almost without change.
* This includes a severe refactoring of adding nodes in general in the Graph Editor. The whole responsibility of adding new nodes (and starting their editing) was moved to Graph Editor - the Project View only reacts for GE events to show searcher properly.
* The status bar was moved from the bottom-left corner to the middle-top of the scene. It does not collide with (+) button, and plays "notification" role anyway.
* The `interface` debug scene was buggy. The problem was with one expression's span-tree. When I replaced it, the scene works.
* I've removed "new searcher" API, as it is completely outdated.
* I've changed code owners of integration tests to GUI team, as it is the team writing mostly the integration tests (int rust)
Implementation of the Text take and drop APIs
- Added `Range.contains` function
- Added `Text_Sub_Range` type
- Added `Text_Utils.index_of` and `Text_Utils.last_index_of` based on ICU StringSearcher
* Add matching mode definitions
* Add stub for new method API and an initial test suite
* Fix tests, implement exact matching
* Implement Regex matching
* changelog
* Add benchmarks
* Wokraround for case insensitive regex locale support
* minor tweaks
* Unify Case_Insensitive
* Update edge cases
* Fix other affected places
* minor style change
* Add a problematic test
* Add a regex test for a similar situation
* Migrate to StringSearch:wq
* Add test cases for scharfes S edge case
* Add problematic Regex Unicode normalization test
* Document the regex accents peculiarity
* Do not apply the normalization in ASCII only mode
* cr

This is a reincarnation of PR [3273](https://github.com/enso-org/enso/pull/3273).
The maximum zoom factor of Graph Editor is limited to 1.0x. It is not possible to zoom in from the default camera position.
Debug Mode (activated with `ctrl-shift-d` shortcut) allows to zoom up to 100.0x (the previous behavior of Graph Editor).
If you enable Debug Mode, then zoom in and disable Debug Mode - you won't see the immediate change of zoom factor back to 1.0x. But it will "jump" (with animation) back once you make a zoom in/out event with your controls.

# Important Notes
This is a reincarnation of PR [3273](https://github.com/enso-org/enso/pull/3273). There are two changes since that PR:
1. Fixed bug with GeoMap zooming described [here](https://github.com/enso-org/enso/pull/3290). This is done by restricting `ZoomEvent` API so that it will never contain `amount` which is equal to `0.0`.
2. A few refactoring changes from https://github.com/enso-org/enso/pull/3289 to simplify code a bit.
* Integer parse via Longs
* Integer parse via Longs
* Benchmark for Number Parse
* CHANGELOG.md and Natural Order
* Expanded test set
* Number base tests
* Few more negative tests
* Implement Natural_Order and sort_columns
* Starting on Rename
Align Column_Mapping
Add By_Position
Separating off the validation for By_Index so can reuse for rename
By_Position implemented
By_Index implemented
Adjusted behaviour following discussion with Ned, so that renames dominate untouched columns.
Moving to validation style checks for problems
Putting accumulator back
Rename work
* Add Range.find
* More work
* Regex support
Tidy of Unique Name Strategy
* Fix Regex support
* Warning messages
Tests for Unique Naming Strategy
Table rename working
* Database Table rename_columns
Fix for Table
**Must follow up on slice**
* Some tests
* More tests
* Complete test set
(and associated fixes)
* Functional use_first_row_as_names
Tests to go...
* Test for use_first_row_as_names
* Change log
* trailing space
