    StButton: fix handling of Space/Enter -> click
    
    StButton was mistakenly considering any Space/Enter KEY_RELEASE to be
    a click, when in fact it should only count as a click if it also got
    the corresponding KEY_PRESS as well. This meant that when typing in a
    chat notification, any Space/Enter keypress would dismiss the
    notification, since the StEntry would take the PRESS event but ignore
    the RELEASE, allowing it to propagate to the notification itself,
    which would treat it as a click.
