Baking for dupligroup & linked library objects

- library data allows pointcache writing (hard to know how this should work long term so ifdef'd for now)
- changing the frame now updates the dupligroup objects
- BKE_ptcache_ids_from_object(), option to get the id's from duplis

note! scene_update_tagged() is called from the main() loop, and runs BKE_ptcache_quick_cache_all(), this could become a performance issue, especially with duplis, should probably not call BKE_ptcache_quick_cache_all() all the time, even when not playing back animation.
