Moving urls.pyu

I moved urls.py from regserver to regulations as it's supposed to be part of the app and not the project. I also fixed some tests that rely a little closely to the url structure. I don't think that changes the meaning of those tests. 

I set up the urls.py in regserver to respond to both /partial/... etc as well as /eregulations/partial/... etc. This let's us  test both for now.
