Angular Colorpicker

An angular colorpicker for use with angular views. Fashioned after [jQuery Minicolors] (https://github.com/claviska/jquery-miniColors/).
I'll definitely use the ```var showColor = convertCase(scope.color || '#ffffff')``` line, as it's much more succinct.
I'm not suer convertCase() makes much sense as a local method though, because I do use it in `minicolorsPicker` as well. I could probably put it in the service though, like the `parseHex` method.
