This version adds global variables to CustomItems, so you can now do things like store the total number of times all of your players have slain creepers with the "creeperSlayingSword", or even make quest books! An example of a quest book will be uploaded on the wiki soon.
To use global variables, just use the normal actions/handlers/placeholders for variables, but replace "variable" with "global" — it's that simple. You can also store per-player global variables by including {player.uuid} in the name of the global.
