Adding socks5 support to python-irclib

I was playing with IRC and Proxyes a few weeks ago, and I found out that python’s irclib didn’t support them!
It took me like a minute or so to fix it, just overloading socket with socksocket, you can have a look at my fork in github

        try:
            import socks, os
            socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5,
                os.getenv('proxy_addr'), os.getenv('proxy_port'))
            socket.socket = socks.socksocket
        except:
            pass

So, basically I try importing socks and setting up a default proxy, socks5 (sorry, I haven’t considered socks4 on there), with the environment variables proxy_addr and proxy_port as addr and port.

To use it, you’ll have to get a libirc-based application (there’s a bot included that might be a start) and, before starting it, define proxy_addr and proxy_port

proxy_addr=127.0.0.1; proxy_port=1080; python my_python-irclib_based_foo

Enjoy =)
