* Refactor: Move the responsibility for applying physics and sending the initial client update to Scene.AddSceneObject() from some of the SceneObjectGroup constructors

* I think this has been done cleanly from inspection and testing, but if prim creation or load suddenly starts playing up more than usual, please open a mantis
* This also has the effect of stopping the archiver generating ghost in-world prims
* Some code dupliction also removed
