Update to V0.0.1

Hi 

Here is a start for this repo.
Like [testacular was renamed](https://github.com/testacular) I'm now using [Karma](http://karma-runner.github.io/0.8/index.html) that is really the same thing...
Thus I replaced _grunt-testacular_ with [grunt-karma](https://github.com/karma-runner/grunt-karma), and I simplify the _gruntFile_ following [the doc](http://karma-runner.github.io/0.8/plus/Travis-CI.html).
The rest is just fixes where the [directive ui-codemirror](https://github.com/angular-ui/angular-ui/blob/v0.4.0/modules/directives/codemirror/codemirror.js) becomes a __module ui.codemirror__

Let me know of your suggestions, if any ?
