Support redirect for ports other than 80 and 443

As far as I have heard here on the forum is that the CA/B Forum doesn't allow other ports to be used, even when redirected.

See for more information: Ballot 169 – Revised Validation Requirements

Authorized Port: One of the following ports: 80 (http), 443 (http), 115 (sftp), 25 (smtp), 22 (ssh).

By the way, as far as I can see, the BR doesn't mention any reference to redirecting. Not allowing it nor dis-allowing it.
