Rewritten and migrated Gradle to Kotlin DSL, now shadowing will include only required code and minimize it.

Due to deprecation of CompleteConfig the mod now uses direct Configurate implementation which resulted in differences in config files, this means that old configs are not compatible and must be migrated manually.

Now channels presented as id and categories, this allows flexible configuration and gives ability to display only required information.

Messages moved into separate config and have new structure, more info can be found on wiki.
