Made X-Editable includes/config page-by-page and auto-progression. 

@codesliced Ready for review.

Did this only for the first student page, but this approach will be helpful for the subsequent pages.

Changes include:
- X-Editable config can go on the individual page that has the fields, rather than in a global JavaScript file (better load time, easy to find fields, prevents namespace problems with duplicate IDs)
- Added some code to auto-progress the fields (not sure if there's a good way to make this global, currently on the first enrollment page and needs to be included on subsequent pages). Image attached of auto-progression.
