mb-applet-blanker todo list.

* Exit/Killed
  If the applet exits or is killed it should attempt to enable anything that
  has been disabled (backlight, screensaver, suspend).

* Low priority

  - Usage message (still using the old mbmenu one)

  - _MB_THEME error on startup

  - Only reset backlight on startup if it's currently off
    Just in case it was our fault (due to the app crashing or during testing)
