When removing a skin or multires modifier, it skips deletion of the associated CustomData layer if the object has any other modifiers of that type. This check has been extended to all objects that use the object's data. Similarly, deleting higher multires levels and multires subdivision will not update the maximum level of any other multires modifiers on objects that link to the same mesh. Note that modifier_apply_obdata() doesn't need any changes as it does not allow applying to multi-user data. Object joining has also been modified to synchronize multires levels objects that share a mesh. This is needed because joining can subdivide or delete levels in order to match the maximum level of the join-from object to the join-to object. Fixes bug [#31880] instance multiresolution modifier error. http://projects.blender.org/tracker/index.php?func=detail&aid=31880&group_id=9&atid=498 Reviewed by Sergey: http://codereview.appspot.com/6332047/
