Add stack bower + yeoman + grunt in project

Add stack ```bower``` + ```yeoman``` + ```grunt``` in project, based in generator-angular (https://github.com/yeoman/generator-angular). Some files, like ```jsyaml``` and ```lodash``` now is included in angular like ```angular.factory``` for more flexibility in your use between angular application.

Now you can use ``` karma + jasmine``` (already used and integrated in project)  and ``` protractor``` (https://github.com/angular/protractor)  for e2e test too.
