Tons of damage

Hi

Here is the new face I propose with :

 - Some clean up and unification of coding style for Karma and Travis.
 - A tiny task to concat all the dependencies of the main module `ui.utils`. 
 - A refactorization of the concat task.
 - A banner fix.
 - A _jsHint_ task.

If It's too much on one pull request I can split it to focus on what is really necessary.
