Allow setting IP to listen on.

Browse Source 
Running on bare metal, 127.0.0.1 is a sensible choice of address
to bind on, but that is not the case when running inside a
container, so we add the ability to choose which IP to listen on.

This can be given via the environment variable HTTP_HOST when
starting the server or, if used as a module, as the second
argument of the start(port, host, path) function.
