CodeMash REST Endpoints Updated

You spoke, we listened.  We've got updates to the CodeMash REST endpoints!

We've added two new pieces of information to the Sessions feed: Track and Room.  Track exposes what track a session is part of (for filtering, etc…) and Room indicates which room the session will be held in.  Note that the room information and start time have not been finalized and are subsequently empty.

Also, the speaker submission form was designed during a heated battle for control of a coconut tree so we forgot to ask speakers for their twitter handle and blog URL.  We're collecting that info now and as it trickles in, we'll get our database updated and you'll see the information in the REST feeds.
