* mandos-ctl (string_to_delta): Try to parse RFC 3339 duration before
                                anything else.  This also minimizes
                                the changes from the last release.
  (PGPEngine): Use straight subprocess.Popen() to call "gpg".
* mandos-monitor (UserInterface.run): Fix grammar.
