Formalize the concept of a NonPage that can appear in the site-map, useful for

into NonPages in the site-map.
Also, pass page=self to every view as a keyword argument when generating the
Django urlpatterns.

Add a relative symlink pointing at ../rietveld/upload.py in thirdparty/chromium
so that gcl.py can import the thirdparty/rietveld/upload.py module.
