web-routes, upd8, write: integrate web routes with url-spec

[Note: due to a fantastical Rebase Fail Moment, this commit
 accidentally reintroduced some bad imports in upd8.js that
 are meant to be factored into #import-heck. So this commit
 is rewritten to not do that, but it means the commits in
 pull requests #442 and #479 don't line up with main history
 like they should. Oops.]
