Subject: Major changes in interregion communications. This breaks
compatibility with older versions, and may result is all sorts of weirdnesses
when interacting with sims in older versions. Changes: - Introducing
synchronous Teleports. Now the receiving region calls back the sending region
after the client has been made a root agent there, that is, after client
sends CompleteMovement to the destination. - SendCloseAgent moved from OGS1
Remoting to RESTComms.
