Unexpected behave with FTP-Proxy = transparent w/o User/Pass

[uprinz]

If the FTP-Proxy is set to transparent but no User /
Pass is provieded the client issues USER command even
there is nothing to tell the firewall server. It would
be better not to send the USER / PASS commands but just
use the RemoteID@Remotehost without any other commands.

This would enable another class of FTP-Firewalls to be
usable by FileZilla that just expect a connection
request without any USER / PASS commands.

This solution will also improve the setup handling as
it enables another version of firewall settings without
adding another radio button.

That's actually the whole point of a transparent proxy, it's supposed to know what the user wants.
