Integrating Runtime Version Manager with Project Manager (#1285) 
Related to #1153, implements the first part of the integration, without the
parts that use the runner which will be done next.
Temporarily there are two logger implementations - this will be alleviated with
the next part - when and the direct classpath dependency on the language server
is removed.

Fix Storing the Runtime Types (#1271) 
A bunch of improvements to the suggestions
system. Suggestions are extracted to the tree data
structure. The tree allows producing better diffs
between the file versions. And better diffs reduce
the number of updates that are sent to the IDE
after a file change, and consequently fix the
issue when the runtime type got overwritten with
the compile-time type.

Handle Rename Command Properly (#1041) 
In the current workflow, at first, the default Unnamed project is
created, and the Suggestions database is populated with entries from the
Unnamed.* modules. When the user changes the name of the project, we
should update all modules in the Suggestion Database with the new
project name.

This PR implements module renaming in the Suggestions database and fixes
the initialization issues.

- add: search/invalidateSuggestionsDatabase JSON-RPC command that resets
  the corrupted Suggestions database
- update: SuggestionsHandler to rename the modules in the
  SuggestionsDatabase when the project is renamed
- fix: MainModule initialization

Update ExpressionValueUpdate Notification API (#1033) 
ExpressionValueUpdate notification contains information about the

notification adding the suggestion id of the executed object.

- update: public API for ExpressionValueUpdate notification
- update: ContextEventsListener groups ExpressionValueUpdates and sends
  them in a batch
- update: ContextRegistry listens to the notifications from runtime and
  routes them to the corresponding listener.
- test: add ContextEventsListenerSpec

Fix a bug with compiler metadata (#838) 
1.  The metadata objects weren't being duplicated when duplicating
    the IR. This meant that the later passes would write metadata
    multiples times into one store (reference), causing wrong
    behaviour at codegen time.

Add task fixing Instruments compilation. (#814) 
Incremental compilation of instruments may lead to runtime errors when
only some of the instruments are recompiled (because the unchanged
instruments are not registered by the Annotation Processor).
To fix this, we add a task that ensures all instruments are recompiled
when at least one of them changes.
