Manifest.json Support

[Lite5h4dow]

Enhancement Type

Improve an existing feature

Describe the enhancement

Exported Client modpacks use Manifest.json to communicate the modfiles that are used as well as forge version and minecraft version documentation here: https://nodecraft.com/support/games/minecraft/preparing-minecraft-modpacks-manifest-files#h-downloading-server-files-d06c460319

it is reccomended that you use a mod scrubber when doing this manually to avoid client mods that crash servers such as this one: https://github.com/BloodyMods/ServerStarter however given this also starts the server, might want to ignore it and just state that client side mods may crash the server.
