    actor: Use g_clear_object()
    
    GLib has a nice, atomic object clearing function that allows us to drop
    code looking like:
    
      if (priv->object != NULL)
        {
          g_object_unref (priv->object);
          priv->object = NULL;
        }
    
    from the ::dispose implementation.
