Static override: enhance 'make override' operator.

Now when you make an override of a linked armature, code will
automatically also override objects using that armature (deformed by, or
children of), trying to replicate make_proxy results.

Also some initial code to replicate 'make_proxy' in case of instantiated
linked groups, but that is not working yet (and will also require some
work in RNA part of group's objects collection anyway).
