Title:  	Added CUPS and ftp to Safe_ports

I think we should include these ports onto Safe_ports per default, given they are included as Safe ports, and most ftp clients will use http connect when proxied, and it is a common practice to allow web cups interface to be reached only with https (CONNECT method again)
