* Stop nulling SOG.m_rootPart and parts on object deletion

* This renders RootPart == null checks useless - the replacement is to check SOG.IsDeleted.  However, in many cases this will not be necessary since updates to deleted parts 
will not be sent to the client
* This should remove any remaining race conditions where an object is deleted while another thread is yet to obtain the root part to perform some operation
* Doing this is probably a necessary prerequisite to moving to a model without a separate SOG and SOP
* Unfortunately it's not possible to eliminate all RootPart == null checks since in some contexts it is currently used to check whether an object was created successfully
