JS to power Websockets

The server side isn't quite there yet, but this is all the code needed to power websockets for Pebble! (You can't do much with this yet, although one thing you can do is make the C code handle different GUI scenarios. So add a message from Javascript --> Pebble that means "make this a button I can tap by tapping my watch" or something like that :D. Grab me in person if that doesn't make much sense.)
