Mantis #2111 

Eliminate gretuitious KillObject packets. KillObject is sent to the
viewer for the root part only.
Also prevents the full update on deselect that makes a deleted object
reappear and stay visible until the background deleter got around to it.
We still send 2 KillObject packets for the root prim, that could be 
avoided only at a cost in reliability. One packet seems an acceptable
price to pay for consistency.
