[metacity] Add support for switch-applications keybindings

[Jeremy Bicha <jbicha src gnome org>]

    Add support for switch-applications keybindings
    
    In gsettings-desktop-schemas 3.8, there is not shortcut for
    switch-windows, and Alt+Tab points to switch-applications by
    default.
    
    As we do not support switching applications, but want Alt+Tab to
    work, just bind switch-applications to the same action as
    switch-windows is currently bound to (and the same for -backward).
