fix the way http verbs are defined

I changed the way they are defined so that they are more IDE-friendly. The way they were defined, an IDE wouldn't easily recognize them and would often show 'request.get' or 'request.post' etc as a possible error. Ctrl+clicking on the 'get' function wouldn't take you to where it was defined. Now it will!
