[clone] Allow painting hidden source actors

Browse Source 
With the introduction of the map/unmap flags and the split of the
visible state from the mapped state we require that every part of
a scene graph branch is mapped in order to be painted. This breaks
the ability of a ClutterClone to paint an hidden source actor.

In order to fix this we need to introduce an override flag, similar
in spirit to the current modelview and paint opacity overrides that
Clone is already using.

The override flag, when set, will force a temporary map on a
Clone source (and its children).
