Changed Jump-To-Definition, as requested -- modeled on QuickEdit:

  - Now can register multiple jump-to-definition providers (only one, so far).
  - Moved jump-to-definition menu setup to top level.
  - Added jump-to-definition to floating right-click menu. [ Note: we may not want
    this unless there is a provider registered for the current mode, but that's how
    QuickEdit does it.  We can fix both at the same time if we decide to. Also note
    that if we want to change the right-click menu for this, one could argue that we
    should also change the top level menu for the same reason. ]
Commented out JUMPTO_DEFENITION from right-click context menu.

Kill and restart the codehint worker thread every 30 hint requests.

This avoids some memory leaks that we were encountering.  Still looking into those, but this should at least stabilize things and prevent the memory from growing so much it crashes brackets.

To avoid a noticeable performance hit when we restart the worker, we instead start a new worker, and only switch to it after it has finished intializing (including priming the pump).  So when we switch between the old and new worker it should be unoticeable to the user.

Had to move around a lot of code in ScopeManager - there are not a lot of actual changes, but the diff is messy due to this.
