Adding config module [WIP]

- [ ] come up with a way to pull relevant data out of `package.json`, maybe `.bowerrc`
- [ ] introduce a `deps` array in `config` module to load external dependencies
- [ ] make `config` module resolvable via `config:main`

I started gathering some thoughts about `config` for EAK [here](https://gist.github.com/twokul/e6df7a5c0cda716a9d6f)
