- This commit should satisfy all notes from Chris' code review.

- Reference to the new JSON feed is commented out in campusController.js so this can go live any time without affecting anything else. Just toggle that when ready.

- Sorry I didn't have time to work on data import/export, but we felt it was more important to get the data structure right.
