hgweb, spartan: add "URL breadcrumbs"

hgweb, spartan: add "URL breadcrumbs"

This change adds a "URL breadcrumb"  to the "title" of the pages on the spartan

selection row, which shows the name of the page that is being viewed, along with
some additional information.

In doing so it standarizes those "titles" which now follow the pattern:

URL breadcumb / page details
