Subject: Started to cleanup/close down childagent connections when a user
 teleports.  As the client will not close old childagent connections without
 being told explicitly to do so by each region the connection is to. Currently
 only implemented in standalone mode. ( the  TellRegionToCloseChildConnection(
 ) in OGS1GridServices.cs needs implementing for grid mode, and the inter
 region .net remoting added for the new messages). hopefully fixed the echo
 bug in chatmodule.
