Allow Custom IP to bind to

[lionkor]

Currently you can specify a custom IP via the first argument to the server. It's then subsequently ignored by the backend.

The entire thing needs to be an optional config setting, and then be bound to with bind() so that we can ensure the IP is actually owned by the server.

Needs to work in docker/pterodactyl, so ensure we can still check the IP by bind()ing to it

Is this still being worked on?

[lionkor]

Yes, but I'm currently taking a bit of a break from the project.

[lionkor]

But this is still planned and prioritized
