    window: use the right signature for button-release-event callback
    
    The signature is (ClutterActor, ClutterEvent). Using the event source
    there is wrong, as that's not guaranteed to be the same object emitting
    the callback (i.e. the object emitting could be just forwarding an event
    coming from one of its children).
