Bind WireServer to localhost only in order to avoid firewall prompts

[nre-ableton]

This change fixes an issue in macOS where the firewall makes annoying prompts which require one to allow the application to listen for incoming connections. This dialog is shown every single time the application launches. By providing an additional override to listen(), one can configure the application to listen on 127.0.0.1, which prevents the prompt from being shown.

I would expect a change to the command-line interface for this change too. Additionally I would expect you to add a test case to verify both listening on the any and localhost addresses.
