commit ab0460ad5926aef2cb802f201069109ce9fc2dd8
Author: Colin Walters <walters@verbum.org>

    Use clutter_actor_destroy in dispose, add _dispose where needed
    
    ClutterGroup calls _destroy, but most of St was just calling _unparent.
    This caused problems because the DESTROY signal was not emitted
    for child elements after destroying a toplevel.  Also, in a GC'd
    binding it would cause unpredictable lifetime of children.
    
    Some St widgets simply didn't have _dispose at all; implement it.
    
    Note because of the usage of the background_image in StButton,
    we can't cleanly destroy it inside the StWidget.
