Replace Game Side config with Web UI config.

[Claycorp]

Currently as there are multiple version of the mod (Bukkit/Forge/Fabric?) and each system has it's own unique config system it makes generalizing or auto-generating the configs annoying.

As this service already relies on the linking server being available everything should be done via the web UI. Servers would be linked to an account/user/whatever by the server generating a token that is then used on the web side. Otherwise a token could be generated from the web and stored in a file on the server instead.

This removes the issue of end users messing up the unique files, needing to make 4+ config generators and simplifies providing support.
