Moved prim crossing out of OGS1 and into RESTComms and LocalInterregionComms. This breaks interregion comms with older versions in what concerns prim crossing. In the process of moving the comms, a few things seem to be working better, namely this may address mantis #3011, mantis #1698. Hopefully, this doesn't break anything else. But I'm still seeing weirdnesses with attchments jumping out of place after a cross/TP.

The two most notable changes in the crossing process were:
* Object gets passed in only one message, not two as done before.
* Local object crossings do not get serialized, as done before.
