Added bStats support. With bStats I'm able to check how many times my plugin is being used, where and lots more. You can disable it by going to: "plugins folder -> bStats -> config.yml -> set enabled to false".
Added fully compatibility for 1.8x - 1.13x. Before the plugin was coded in 1.12.2, but as the sound names were different in 1.8,1.9 and 1.13, it gave an error when enabling the plugin and then it shut itself down. Also the item names got fixed as they are different in 1.13.
