Migrate to a clojurescript, web-based interface.

[CmdrDats]

This will make the user interface a whole lot easier to develop for, since you won't need to reinvent simple stuff, like input boxes and buttons - especially important when we get to heavier UI requirements.

When the app starts up, fire up a local web server and automatically open up a browser (?) to the endpoint.

Treat each new browser as another 'guest' view - in the future, they can 'take a seat' as a player (can provide their name, rank and, optionally, their OGS details) - or they can simply be an observer/commentator, possibly with hidden commentary and branching analysis that can get included in the final SGF.. that kind of thing..
