Handling of RigidBody data in duplicate of scenes/collections was very wrong. This commit: - Add handling of duplication of RB collections when fully duplicating a scene. - Fix Object duplication trying to add duplicated RB objects to matching RBW collections. While the later behavior is desired when only duplicated objects, when duplicating their collections and/or scenes it is actually very bad, as it would add back new object duplicates to old (RBW) collections.
