1.8.5 - 1.17 support, MC-164316 fix and removepack command
Added 1.17.x support and pack format 6
Added command to remove packs (/<command> removepack <pack>)
Added workaround for MC-164316 by applying the file-hash to the URL. This might increase the client-side storage requirement but will correctly re-download new versions of the packs
Fix editing of the global assignment via commands not saving to config
