* Reorganized the configuration file to be organized per tool under a "Tools" category
* Removed the "Enchantments: SilkTouch / Fortune" configuration options as these are automatically set to true due to NMS usage
* Added "WEB", "LEAVES", and "LEAVES_2" as default Shears blocks
* Increased max iterations from 10 to 15, as some issues were occuring with larger amounts of vein counts
* Slightly restructured the veinminer listener so it's ever so slightly more efficient
* Fixed "ALL" category listed blocks not being breakable by all tools (as it should be)
* Fixed tools using durability even if "VeinMinerUsesDurability" was set to false
* Fixed being able to use "/veinminer toggle" if the player doesn't even have any actual veinminer permission nodes
* API: Added a "public static getPlugin()" method in VeinMiner class to get a singleton instance of the plugin
* API: Added a couple methods in VeinTool, "getMaxVeinSize()" and "usesDurability()" to get respective options from configuration file
