Change the listen address

[FritschAuctores]

We have following scenario:

• we use the kube-forwarder with windows 10
• we use docker-for-windows
• a local docker-container must connect to a Kubernetes service

Now we have a problem. The Container can´t connect to the forwarder. So we change the "server.listen IP" in the Connections.js to 0.0.0.0, but that is not optimal. Now every device in our Network can connect to the service.

We need an option to configure the local bind address.

I wanted this as well so I made a PR: https://github.com/pixel-point/kube-forwarder/pull/41

They haven't responded to the PR for a long time, though, so I guess they aren't too excited about it.
