Title: Start of SSH2 Agent Forwarding implementation

As I'm rather keen on having this work I've written code to support a SSH2 Agent Forwarding implementation. This PR does enable this functionality but as I am not super familiar with PHP or the design of this library I'm expecting some feedback or comments.

This PR will address this current OPEN issue / feature request.
