We can easily implement much of the same behavior ourselves by keeping track of Clutter's focus events. Reintroduce heavily modified FocusGrabber to do the work for us. This will temporarily break when the user selects a window until we can make gnome-shell automatically set the stage focus. This also removes our only use of focus grabs, so remove those as well. https://bugzilla.gnome.org/show_bug.cgi?id=700735
