add url view

(great thought, Ethan)

added test, though it's somewhat meager, since the complete url will vary with testing environment.

second example in http://test.dwagn.org/wagn/Menu_url but I think that's already ticketed.

Yeah, same issue as make urls in content work within link syntax. It's about how link processing handles the inclusion, not about what the inclusion yields, so I'd rather track that concern in that ticket.
