mq: upgrade the patch to HG format when adding the author name with qrefresh

When setting the author field with qrefresh (-u|-U), and the patch does have
neither a 'From:' nor a '# User' header, add the author name as such:

- if the patch has a 'Date:' header, add a 'From:' header
- otherwise, upgrade to Mercurial extended patch format and add # From
