no support for ssh -D (SOCKS5)

[cnf]

What happened:
I opened a connection with ssh somehost@portsl -D 3128 and tried using that port as a SOCKS proxy. This works fine if I do an ssh someuser@somehost -D 3128, but going through sshportal, that connection doesn't seem to get forwarded.

What you expected to happen:
For there to be an SOCKS5 capable connection.

How to reproduce it (as minimally and precisely as possible):
Set up sshportal as normal, run ssh host@portal -D 3128, and point your browser to 127.0.0.1:3128 as a SOCKS5 proxy

Should be fixed now

Closing the issue as I plan to work on the v2 of this project and I need to make some cleanup in the issues see #210
