Switch to new webpack and npm workflow

This is a set of changes that matches Blip's new development and build workflow.

Wether you're working in Blip or Clamshell, all commands to remember are the same. Basically:

```bash
$ npm install
$ source config/mock.sh
$ npm start
$ npm run build
$ npm run server
$ npm run jshint
```
