    messageTray: fix clicking on links again
    
    The change to make Notification an StButton (06d2c0af, bug 642978)
    broke links, because the link actor would ignore the
    button-press-event, allowing the notification actor to receive it and
    get a pointer grab, and so the link actor would never see the
    button-release-event. Fix that by accepting and discarding the
    button-press-event.
