Another big checkin.
This includes some significant cleanups to the new course categories
system. The basic idea is that the categories/course browser is now
unified under one system, and admin features related to that have
all been moved into the browser (as little icons).
I'm much happier with this as a foundation that can scale and be
built upon.
Still to go:
- searching
- paging
- polishing
Also in here are a lot of little cleanups around the place, such as
the initial setup process.
