@url decorator improvements

A slight modification (and, I think, improvement) of the URL decorator found in snippet 395.

What's different between this snippet and 395?

  1. We use django.conf.urls.defaults.url() when adding patterns
  2. We support arbitrary arguments to the url() method (like name="foo")
  3. We do not support multiple url patterns (this didn't seem useful to me, but if it is I can add it back.)
