Added BackgroundModeManager which tracks when background apps are loaded/unloaded

and puts Chrome into BackgroundMode appropriately.

Added EXTENSION_UNINSTALLING notification which is sent out when a notification
is about to be uninstalled.

Refactored StatusTray code to move StatusTray under the profile rather than
attaching it to the browser process, and removed StatusTrayManager which is
no longer needed now that BackgroundModeManager handles creating status icons.
