Warn system and kit command

In this update I have added the kit command and the whole warning system, but they are currently in Polish. The English translation will have to wait, but it should appear within 3-4 days. The id command issue has also been fixed. In order for it to work, you need to delete the entire config.yml file and the languages folder and type the command 'yourserver reload'. Permission for commands from the warning system will also be added in the next update.
