Feature/npm semantic versioning

As is the version causes dependency installation with `npm install` to fail:

```
npm ERR! install Couldn't read dependencies
npm ERR! Darwin 13.3.0
npm ERR! argv "node" "/usr/local/bin/npm" "install"
npm ERR! node v0.10.32
npm ERR! npm  v2.0.0

**npm ERR! Invalid version: "2.0.1.5"**
npm ERR!
npm ERR! If you need help, you may report this error at:
npm ERR!     <http://github.com/npm/npm/issues>
```

This is because npm requires [semantic versioning](http://semver.org/), which follows the pattern: MAJOR.MINOR.PATCH-pre-release-label.

Looking at the history 2.0.2 seems to be the appropriate patch number, but you probably know best.
