Release version 2.0.3

# Fries v2.0.3

A few additions and fixes before moving on to `v2.1`. This is more like a documentation update rather than features.

* Documentation now runs on Jekyll
* Removed `grunt-connect` since we're now using Jekyll
* Made Stack.js async
* Made the component examples bleed on screens `< 480px`
* Adds [Add to Homescreen](https://developers.google.com/chrome/mobile/docs/installtohomescreen) support in the examples.
* A few bug fixes
* And lastly, Fries gets its own domain. Check out the documentation at http://getfri.es
