Removed cycling menu items from app menu; users can go to the actual menu for that
Rewrote the toolbar button overlay, primarily for Australis support

But all supported applications now get a much better toolbar button. No more puzzling icons, just the input method name. When AVIM is off, the input method is crossed out.

When upgrading to Firefox 29 (which has Australis), automatically hide the status bar panel and add AVIM to the toolbar.
