Make basic object & bones transformations overridable.

You can now override loc/rot/scale of objects and posebones.

Also added a basic operator to make an override of active linked object,
but this is very limited/wip/testing feature (you have to manually override
object and its armature, and relink to proper local overrides
yourself...). Final 'make proxy killer' will be much more automated of
course.
