Updated todo.
Added autoslug field.

I've been bad, and not provided a working South migration for this. The
work-to-reward ratio got bad; there's no real data yet, so I can nuke the DB.
Added pagination.

Still needs some styling.
Ticked down some settings, to test pagination.
Added tabs for media types.
Added remember-where-you-were to login link.

Even detects when you're on the logout page and *doesn't* redirect
you back there.
Clean pagination with custom querystring handling.
Final touches on search.
