Refactor angularjs code to use gulp

[IMS94]

The angular JS code used in this app is written inside public/js which is not the correct place where it should be. It should be moved to resources/assets directory and use gulp task to output one js file to the public directory.

@IMS94 I'd like to work this for you, unless someone else has already

[IMS94]

@JaredsCode Great! Go on. Ask me if you need anything clarified.

This issue needs a bit more information. As far as I can see there are a lot of JS files in the public directory, but not all of them appear to be in use. Is there a list of files that should be compiled into one? Should the gulp script concatenate all the files currently listed in the layouts.master and layouts.app blade templates or should it just copy them?

@lachieh For the moment, including all the files in public/js into one file is enough. Then we can add the resulting file to latouts.master directly.
