Had to rename Rotation in SceneObjectGroup to GroupRotation to stop conflict with Rotation in entitybase (couldn't override as they are different types (LL vs Axiom) and didn't want to add new).

When you take prims into inventory (or delete them), they should now be removed from the prim datastore, so they no longer reappear in-world when you restart opensim.
