Style 05-04: Extract Template and Styles to Their Own Files

[abollini]

Switch to always use the templateUrl directive https://docs.angularjs.org/guide/directive

The template file should be named as the component file with the .html extension

I started this process. Unfortunately, it is not yet functional with angular universal. The server side seems to require absolute paths while the client side uses relative paths.

angular/universal#294

I created a branch with the restructuring but still using template rather then templateUrl.

I did not put in a pull request due branching from a branch waiting on merging.
