Subject: Error on generating Atom feeds without an author

RFC 4287 requires every feed to carry an atom:author unless all of its
entries carry one. Entries here never do, and the feed-level author was
emitted only when params.author was set, so any site that did not set it
published feeds that no conforming validator accepts.
