Force a relayout when showing an actor

Browse Source 
When an actor is hidden, the parent actor is not required to
size request or allocate it. (ClutterGroup does, but, for example,
NbtkBoxLayout doesn't.) This means that the
needs_width_request/needs_height_request/needs_allocate can be
stale when we go to show it again - they are set for the actor
but not the parent. Explicitly setting them to FALSE avoids
clutter_actor_relayout() improperly short-circuiting.
