Created migrations, models, and virtual attributes on Question Model for Tags -Microchallenge

Currently, there are some naming issues we hope to refactor, particularly under :tag_namez, but it is working code at the moment.  In addition, we created a getter and setter method on the Question model to parse the tags created for the user. We seem to have some merge conflicts with the other micro-challenge - pulling down to clean up commit history.

on application.js - not quite sure what's happening, but pushed changes to origin. Removed js from main application file.
