The Three Classes

This your average Class Mod. It adds three classes to the game: Miner, Soldier, Athlete. The miner gives you an iron pickaxe with various enchants, as well as haste 2. The soldier gives you an iron sword with various enchantments, a shield, and strength. To select a class, you will be given a "Class Book" when you first create a world, where you can then select one of the three classes once you open the GUI. You may wonder why you take damage once selecting a class. It's simple: I couldn't figure out a way to close the GUI once you select a class, meaning you could select multiple classes, so I just made you take 19 damage every time you click the button, so clicking it twice would kill you, and you don't get the items till you close the GUI(I think). This mod is not multiplayer-tested, so only use it in singleplayer, at least that is what I suggest.
