Fritz grunt releaser

Problem
======
releasing stuff sucks.

Solution
======
* Update changelog automatically (with release notes that are manually added)
* Test, build and release the Dist folder as a tag on github.

Grunt script is here: 
https://github.com/fritzvd/grunt-lizard-release

TODO
====
* Change ansible deploy.
* Make grunt script take arguments.


HOW TO TEST
============
Checkout this branch. And branch off from this branch (so you don't pollute this working tree).
Then run `grunt release`. It should do magic and release a new tag on github. (at the moment there might be a conflict with 1.0.2, so change your package.json to e.g. 1.0.3).
