Tor support

[nemesis7331]

I need to use pydle with Tor, so i did a dirty modification in connection.py:

import socks
import socket
socks.set_default_proxy(socks.SOCKS5, "localhost", 9050)
socket.socket = socks.socksocket

Do you think it could be a feature to add in a proper way? If so I would be glad to help.

Proxy support seems fine to add, I'd welcome such a feature!
