Working fork

I see some unmerged PR's attempting to fix issues. Even with those PRs I was not able to make this work on my system. Also since this has not been updated since 2 years I searched for alternatives.

If you, like me, just search for a working solution, you can try https://github.com/abrugh/docker-ssh-agent-forward. It's a fork of this one and worked right out of the box for me.
