Add keybinding manager, to enable binding of custom hotkeys with applets, desklets
and extensions via muffin
remove not needed line in .install file
Allow custom keybindings to be invoked during a modal state (popup menu or other
clutter actor open)
Remove hardcoded Super_L key for closing the menu applet - added a muffin call to
check for current overlay key.
keybindings.js: change xlet to 'custom'
Improve keybinding setter widget for applet settings.  Properly handles
modifier keys across all platforms instead of relying on Ubuntu-specific
code for special modifier key handling.
keybinding widget: Fix initial un-set state, refactor
keybinding widget: a little more refactoring
keybindings: A bit more cleanup
