A lottt of stuff from a while ago!
I'm just committing it all together now because I'm lazy.

Frontend:
- Improved course list/view/editing
- Upgraded to Bootstrap 3
- Gave up and used Glyphicons instead (does Font Awesome support v3?)
- Moved js files into /js/ and created separate files
- Minor changes in HTML structure and CSS (design, transition, etc)
- Commented out <details> in login lightbox; no longer mentions RCMS

Backend:
- Merged AccountResource and UserResource classes
- Course now has an info field
- User and Course constructors now take an ID, id field now private

Misc
- Updated README.md a bit
