Plans
=====
* Move processing to background to improve responsiveness of the IDE
* Modularize VCS repo info (re-use clients from radstudioverins?)

* Add a settings window?

User interface:
--------------
* **Updating**: we're currently using the TActions' OnUpdate event to refresh the current repo's
  information, but that occurs far too often. We should probably:
  * set up a timer to check regularly
  * respond to events within the IDE itself when chances are that something's changed.
  * also, probably observe different timeouts for different things. Getting the remote status is
    (potentially) far more costly than the status of our local work directory.
  * Add a button to do a forced refresh. Use it to indicate automatic refreshing as well
    (`Down := True; try do stuff; finally Down := False`)
  * _It might be a good idea to start with a separate button that does something threaded, to make the setup more simple. One step at a time._
* Figure out how to respond to events ([XE7 help](ms-help://embarcadero.rs_xe7/rad/Notifying_a_Wizard_of_IDE_Events.html))
  - `IOTAEditorNotifier`: Modifying or saving a source file, or switching files
    in the editor
  - `IOTAModuleNotifier`: Changing, saving, or renaming a module
  - ⇒ whenever a file changes, check the file cache and then the repo cache,
    and if we've changed repo, we should switch our buttons' displayed info to
    the appropriate repo. If that repo's info is out of date, it should be

            'GExperts is [...]'#13#10
            + '(c) by Erik Berry and the GExperts Team'#13#10
            + 'http://www.gexperts.org',
            bmSplashScreen,
            False,
            GetVersionStr);
    end;</pre>

* Plug into the splash screen as well (`IOTASplashScreenServices`)

Architecture:
------------
* Split cached info in two parts:
  - final pathname of a file's dir => final pathname of the repo's root dir
    (if the root dir is empty, that would mean we know it's not a repo)
  - final pathname of the repo's root dir => repository info
