Bukkit

Changes:

• Player files now generate from and match the players' account names, not their display names.
• Fixed an issue with the "other" permissions blocking a player from using a command to target himself or herself when they supplied their own name.
• Made the player data loaded into the plugin thread safe to avoid concurrency issues.

Known issues:

• DynamicDifficulty will generate a NullPointerException whenever a mob not found in the list of dynamically changing mobs untargets a player.
