Update publish

- extend ignore list for rsync
- use www-master.torproject.org instead of unqualified vescum
- fix recursive chmod to only try to chmod files that need it
- supported updating with both git and svn instead of just svn
- do not trigger a mirrorrun if there are unreadable files in
  www-master's docroot
