Changes:
1) Added some optimizations to protections that should cut down on some tps usages in the fTimer

2) Added a compatibility fix for users of the plugin Magic, IllegalStack will no longer remove items created by this plugin.

3) Added an option to punish players for trying to put chests on mobs more than once. This option is DEACTIVATED by default, but once turned on a player will be warned exactly once that chests are disabled on horses/donkey/llama etc, if they try again the animal will be destroyed, the player's inventory will be cleared and the player will be kicked from the server. Should cut down on people trying to come on your server and repeatedly put chests on animals. Please note if you turn on the punishment option it will for real for real delete the player's inventory.
