AmkMcAuth

// What is Changed in this version (1.5.0)

// New-Features:

// Capcha system using temporary inventory and selecting a Minecraft-Block on joining a server.

// Passwords can now be used by selecting a Minecraft-Block when Registering, Player Login and Change password,

// instead of typing in a password on then Register, Login and ChangePass commands by showing a temporary inventory. 

// AmkMcAuth uses the placeholder 'menu' where you normaly would type the password itself.

// If AmkMcAuth sees the "password": 'menu' it opens a temporary inventory with random blocks and the 

// player has to click the block the he has set/uses as his password-block.

// Bug-Fix:// Optimized(instantly) MySQL update when changing password, thanks to bukkit-member mdfm28 who made the changes to the code.
