Subject: Try mapping source: and browser: links

This turns out to be less useful than expected, because somehow for
every single link in the wiki, the source repository is not quite in
the obvios plae with cgit.  Might be a cgit configuration issue, but
this gets wonky enough that it's probably simpler just to expand the
JSON file we already have for the filter rules so that it includes
other magic stuff like a URL map for this kind of link.
