    app: make display color management work with the transform cache
    
    Need to connect_after() to the shell's GimpColorConfig "notify" so the
    profile transform cache in gimp_widget_get_color_transform() is
    already invalidated when we call gimp_color_managed_profile_changed()
    in the shell's notify callback.
    
    This is a hack. Actually the shell should create its transform only on
    demand, and a config change should simply get rid of the previous
    transform, just as all other widgets are doing it.
