The Recipe Reporting System needs to be able to provide links to commits
in the web interface for the repository, but we can only do this if we
have a custom template URL just like we do for file/tree links, since
it's different for different git web interfaces. Add support in all the
various places for such a URL and make use of it in the RRS.
