Tweak and update the admin UI style.
Review Request #3262 — Created Aug. 8, 2012 and submitted
Tweak and update the admin UI style. The admin UI style has been updated to match the new Review Board UI style. It has the new header bar (though in a yellowish color to signify that it's the admin UI) and bits of the UI match the RB color scheme and images. The admin login page has been replaced with our standard login page. This reduces complexity quite a bit. Rather than fight the Django admin CSS files, we now ship our own version of their admin.css. While we may have to update it as Django updates theirs, it's overall less painful.
Tested each page of the admin UI that I could think of that would be affected, in both Chrome and Firefox.
* Renamed "Dashboard" to "Admin Dashboard." * Shortened a few CSS selectors.
