https://jira.media.berkeley.edu/jira/browse/CLC-2121

Also

* Removed campanile image, since it's not used anymore
* Reorder CSS
* Fixes CLC-2200 - Lots of background images, e.g. the status popover, showing when screens load or are refreshed.
(It touches exactly the same lines of code)

CLC-2236 - IMPLEMENT: when a user can't create an account because of new limits
https://jira.media.berkeley.edu/jira/browse/CLC-2236

Since the 404 and the "Sorry" page are so similar, I used the "Status page" CSS for both of them.
Makes everything more DRY and that's how we like it.
