    Force updating the custom theme dir on change
    
    When changing only the alert sound, changing the links inside
    the __custom theme will not update the directory's mtime, thus
    not trigger gnome-settings-daemon's sound module to flush
    the sound cache, and the old sound would then be used.
    
    Poke at the __custom theme dir when changing the alert sound
    fixes this.
