Clean up my mess :)

Once upon a time, 6 months ago, there was a developer with lot's of faith, but with less Angular knowledge...
... and now he returned and fixed some lines.

Change list:
- Angular version update
- Angular refactors
- better .jshintrc
- consintens single qoutes
- Better bootstrap integration
- Useless tests :/
- Express livereload (in the Grunt/Yo workflow)
