Add the Page object to the context of each view method. Also, add some missing
Arg: sections to __doc__ strings and fix the missing context issue in
editPost() and editGet().

Formalize the concept of a NonPage that can appear in the site-map, useful for
non-clickable sidebar menu divisions, for example. Convert "hacky" fake Pages
into NonPages in the site-map.
Also, pass page=self to every view as a keyword argument when generating the
Django urlpatterns.
