Implement RemoteFolder metrics.

Additional changes:

1. Refactor drawer code to move xml and implementation out of trebuchet.
2. Move RemoteFolderUpdater to overlay, no stub class needed.
3. Pull TrackingEvent.Category out into EventCategory, and create overlay.
4. Remove old sync code from Folder.
5. Prevent RemoteFolder from inserting shortcuts into the database. All
	remote items will exist in memory only.
6. Move RemoteFolder into overlay, and have manager create an instance
	for FolderIcon.
7. Move folder sync out of LauncherModel.

Patch 2: Re-add shortcut click handling in Folder and move EventCategory
	back into TrackingEvent.Category.

Patch 3: Remove whitespace/javadoc/import changes.
