* Added Adventure Mode support for VeinMiner
* Added a permission node to allow the usage of VeinMiner ("veinminer.veinminer". Default: All players)
* Added an onDisable method to clear some ArrayLists just incase some memory is accidentally left over. It's a safeguard, really.
* Added a new "VeinMinerUsesDurability" boolean configuration option to determine whether durability on the tool is used or not (default: true)
* Changed the blocksToBreak array list to public so it is viewable to other plugins, and between classes
