Corrections and additions

In this version I have significantly improved the performance of many commands, analysed what can be done and added as much as I could to some. At the moment there is as much as in the plugin description on spigot.org. To make everything work, it is best to delete the config.yml file and the languages folder again. This is one of the first and last such updates. If there are any errors, please report them to me in a private message on spigot or in the forum of this plugin.
