Sandbox pull 1

@pmuir: I have this updated so it is up to the current revisions and passes most QS tools validation.

I tested it and this is where it stands:

* It builds and deploys successfully.

* I can access this URL <http://localhost:8080/jboss-tasks-angularjs> which redirects to <http://localhost:8080/jboss-tasks-angularjs/#/home>. There are no tasks listed, as you would expect.

* If does not prompt for login. 

    * I assume that is obsolete since the web.xml login was removed. Is that correct? If so, I'll modify the README file to remove the login section. 
    * Also, do they still need to create the quickstartUser or should that be removed?

* I am not able to create a task using the command: `curl -i -u 'quickstartUser:quickstartPwd1!' -H "Content-Length: 0" -X POST http://localhost:8080/jboss-tasks-angularjs/tasks/task1`. It results in a `HTTP/1.1 404 Not Found`. I'm not sure why. Is this still necessary? Did this work for you?

* This shows a prerequisite of the `tasks` quickstart. I don't believe that is true for this one or the tasks-rs quickstart.

Anyway, I figure I'll send this back to you so you can see the updates. I will update package names once you let me know what I should expect to see.
