Write the example config, including every current config option for every module

We will need to keep this file up to date every time we add a config option or change a default.

I wrote this specifically because Ashton wanted to play around with the server but there was no docs on the config options.
We should probably clarify that if this key isn't set at all, the default value is `[ "tcp:6667:interface={::}" ]`.

Also: If you remove the interface, it does not bind all interfaces.  It binds all IPv4 interfaces.  Setting the interface to :: will bind all interfaces.
