Fix external multires data link getting lost on exiting editmode.

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r27742:27859

[#21816] bpy.data.add_image has stopped working on Windows
moved to bpy.data.images.load(), missed this call.

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.

Render Branch: Fix a problem with particle duplis, due to own bugfix for #20350,
the problem for that seems to be in dupliverts, not particles.

Render Branch: Tangent space normal map baking should work again now.
