Subject: Fix to the scenario where we send an agent to a neighbouring sim (via
 teleport), then tell our neighbours to close the agents.. thereby
 disconnecting the user. Added a new CloseChildAgent method in lieu of
 CloseAgent. This has been a long standing problem - with any luck this will
 cure it.
