1. Added to the config settings the first of them, blacklist-list-regions in which you can specify the regions in which the /kb command will not work and discard players and mobs if the player or mob is in a prohibited region in the config you can specify '*' will be blocked all regions, so now the second setting, whitelist-list-regions in which you can specify the regions of which the command will be available, /kb and, dropping mobs, and players, so far it may work crookedly, but it seems to work more or less.
2. Well, messages in each localization file will appear automatically!
3. These settings will be further developed. (Do not judge strictly)
