Config documentation

[C0rn3j]

First of, all thanks for maintaining this mod over the years!

Current config for reference:

{
  "useMojang": true,
  "useCrafatar": true,
  "useCustomServer": false,
  "hostCustomServer": "http://example.com",
  "useCustomServer2": false,
  "hostCustomServer2Skin": "http://example.com/skins/%auto%",
  "hostCustomServer2Cape": "http://example.com/capes/%auto%"
}

The current config options are very confusing. Why are there two custom servers? Does the mod open a webserver with my skins if I turn the server(1) on?

Currently a .json file is being used. JSON does not allow comments. It looks like all other mods I use migrated to .toml files. TOML does allow comments, so if this format were to be used, you could add comments into the config to prevent user confusion, like so, which would make things simpler to understand:

I chose json as it was very easy to load, also vanilla uses them...

It is confusing to have two custom servers. They do serve different options though, but I might just remove the old one later.

A different format with comments might just work, I might change it to something else later.
