* Largely revert the last revision and improve on the previous way of doing things 

* Deleting the object before the async to inventory is bad since if OpenSim crashes (or is shutdown!) in the time inbetween, then the object is lost
* Also now delete the object from the scene only after it has gone to inventory - in the old way there was still a race condition
* This is still not ideal since the 'deleted' object remains in the scene and probably could be manipulated.  But this is better than the alternative
