[mutter] Add 'switch-applications' keybinding

[Florian MÃllner <fmuellner src gnome org>]

commit 2282326f3045d876e71e2eee1fbc3e3cbe087898
Author: Florian MÃllner <fmuellner gnome org>
Date:   Fri Nov 23 03:48:14 2012 +0100

    Add 'switch-applications' keybinding
    
    Add an additional "switcher" keybinding for switching between
    applications rather than windows (like the existing 'switch-windows'
    and 'switch-group' bindings).
    The purpose of the new keybinding is to be taken over by gnome-shell's
    application-based alt-tab popup, so rather than actually implementing
    an application switcher in mutter, let it duplicate the normal window
    switcher when run standalone.
