Change port for SFTP

When connecting to a new address using FTP over SSH (SFTP), it could be nice that selecting this protocol would change port from 21 to 22.
Also, it may be only a local problem, the protocol popup menu doesn't display an icon for SFTP item (after selecting the item, the button takes the same icon as for FTP over SSL)

Sorry, this is more a feature request than a bug report... (at least for the 1st part)
