The presents-specific portions of ConnectionManager like reading Message subclasses and sending datagrams are now in PresentsConnectionManager. PresentsServer should behave identically, except during shutdown. Before, connections would be accepted and datagrams would be read until the OMgr thread exited. Now, both stop as soon as the server begins its shutdown. This seems like an improvement to me, but let me know if it causes issues and I can rework it. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@6270 542714f4-19e9-0310-aa3c-eee0fc999fb1
