Use super static for local server

Just experimenting with using [superstatic](https://github.com/divshot/superstatic/tree/0.9.0) for roots local server. 0.0.9 isn't published yet, so you'll need to `npm link` [this branch](https://github.com/divshot/superstatic).

Not at all complete, there isn't a way (currently) to configure connect middleware for superstatic, so I left infestor out for now. Also haven't really touched the websockets stuff.

We're discussing superstatic's API with the project maintainers [here](https://github.com/divshot/superstatic/issues/64), lots of good work by them to help us get this integrated. Looks like superstatic will eventually expose a middleware interface so we can use infestor.
