    Invalidate states when receiving a focus event
    
    Sometimes we get "focus" events from gtk, but the cache still does not
    indicate that the object has STATE_FOCUSED. Really should get to the
    bottom of this but don't have time to investigate more right now. Might
    be some kind of issue with the accessible being added to the cache
    before it is fully initialized--perhaps AddAccessible really doesn't
    make sense.
