"carch" repo should just be the game

[fengb]

Ideally, the deployed website should be in a separate repo and pull in carch as a dependency. For now, it's here because web isn't production ready and I need to deploy often.

This needs to be done eventually though.

Example:

app.use('/carch', require('carch/server'))
app.get('/carch.js', browserify(['carch/client']))
