Added in a tracker for bStats. This will track what class players choose, and stores the information in a pie chart on the bStats website. This allows me to view, in real-time which classes are the most popular and make the necessary changes to less picked classes or over-picked classes. If you want to disable the data you can do so in the bStats config file.
Added in a clean up on plugin disable to clean up loot chests that where not opened, this is to maximise server performance when using the loot chests feature. Rigorous testing has been done to ensure there are no memory leaks.
