Fixed all issues

Hi Fred,

I had a play with your repository, and managed to get it working. Accept this pull request to see how I did it.

I also changed the way you use bower. Be sure to run `bower install` in the app directory to get all the packages. (I think that is how bower works).

Yours sincerely,

This allows you to refer to the URL `/bower_components/angular/angular.js`, for example.
