Server config - Mission header

A very interesting parameter allows the mod and scenario to be modified directly from your configuration file.

This feature is used, for example, by the ACE Medical mod, which lets you configure certain ACE parameters for your server.
It is also used by vanilla servers to configure a scenario without publishing a separate mod.

The problem is that it is poorly explained https://community.bistudio.com/wiki/Arma_Reforger:Server_Config


A typical server config can look like this:

{
	"bindAddress": "0.0.0.0",
	"bindPort": 2001,
	"publicAddress": "192.168.9.10",
	"publicPort": 2001,
