Make the URLs relative so the admin system can run under a different name.

I decided to run the admin system under a different name to avoid conflicting with another admin system, but it started giving me Werkzeug errors because of the absolute URLs. Now they are relative to wherever they are rendered, which shouldn't be a problem since they are only used by the admin system.

Interesting, I had no idea this would work! Do all tests pass and everything look right to you?

Just tried them and all the tests pass.
