THE BIG ANTI-REMOTING SCHLEP -- StartRemoting is no more. Sims in older versions will have a hard time communicating with sims on this release and later, especially if they haven't transitioned to RESTComms at all.
There's still some cleanup to do on assorted data structures, but the main functional change here is that sims no longer listen on remoting ports.
