    js: Update gestures for updated gesture tracker
    
    With the new gesture tracker, we no longer need the grab-op-begin signal
    handlers since the gesture tracker automatically takes care of this in
    X11 sessions.
    
    Also the gesture trigger edge property has an updated name now because
    it has been moved into it's own class, so use that name.
