Almost useless chat implementation, just added handlers to server and client. Will do more soon, but want to get an initial crappy implenentation in place for sanity.
Fix the double-identify bug in 2 ways. First, if already identified, turn identify into a no-op. Second, instead of immediately requesting re-ident, wait a second, then request every second until a client identifies or disconnects (socket.io seems sane in this event in limited testing).
Make the chat slightly more useful. Add a bare-bones chat pane (on the right, shows up once connected). Since there is no ability to detect user names and such yet, it just posts text there. Needs a lot of work, but need so much other backend stuff done to support it, I just wanted to get this much done.
Merge pull request #1 from dylanryan/master

Fixes for double-auth and a super simple proof-of-concept chat. No UI yet, just console/chatlog to test.
