Bukkit

Updated to 1.7.9. Player files now use the player's UUID instead of their names. Implemented a method of obtaining a player's UUID if they ever joined the server. New players.yml which stores player UUID's and their last known username. New account saving formats: JSON and CSV. Fixed lang.yml failing to load.

Vault is not supported in this version as it has not been updated to 1.7.9 (as of the posting of this version).
