[API Hangouts] Register Hangouts w/Admin Interface & Create Admin Views

[BethanyG]

PARENT TRACKING ISSUE: #160

We will want the ability to review/administer the Hangouts endpoint through the Django Admin interface, and so will want to register our projects app with the Django admin and provide any custom admin views we think we'll need.

See The Django Admin Site, Admin Actions, and Customizing the Admin for more details on how to start.

See Resources : admin.py for an example of how the resources endpoint customized the Admin to display tags appropriately.

---

WARNING: Since hangouts will also include a potential manytomany relation with users, there may need to be additional customization around those relations for the Admin interface.
