Requests timeout and full proxy/socks support

[ramazk]

Sometimes, due to problems with the poe site, the request freezes and hangs until the process is killed, it would be cool to implement a timeout for the request.

I also see proxy support, but as I understand, this is about a local proxy, the port of which is hardcoded into the code. It would be cool to be able to specify the ip:port to the proxy/socks in the request, as well as the login and password for them.
