Allow non-local connections.

Allow non-local connections.

Adding the .withAllowLocalOnly(false) call configures this proxy server to be
more similar to the prior v0_5 configuration. That is it:
1) No longer listens only on 127.0.0.1, required for this test to pass on
machines that are IPv6-only
2) Allows connections from a another machine where localhost would
otherwise resolve to the browser machine rather than the machine the
proxy server runs on (required for running the proxy server on the host
and the browser under test on a VM).
