authentication name. - Use new (ca. 2002) pattern of creating an overridable listener, rather than making the whole class a listener. Mdb told me to add this at the msoy level, but I think it belongs here. Presents simply expects a user to be in one place. It also occurs to me that we probably want something more sophisticated: there may be unpersisted data connected to the session that should be flushed prior to the session starting on another node. We may want something like a lock when users log-in, so that other nodes can terminate the session and flush any persistent data FIRST. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@5635 542714f4-19e9-0310-aa3c-eee0fc999fb1
