Version 1.0.3 - The Dreaded UUID

This release upgrades the database to use UUIDs to identify players. It’s imperative to backup data before attemtping this upgrade. Because Challenges contains commands which do operations on a lot of players at once, a UUID → playername cache file will be prepared. There are two ways to have the file be pre-filled with your existing player data: having lots of world/playerdata files or using GroupManager. Not having either one might cause some slowdowns when certain commands are executed (such as /ch top, /chm list) because of network response time.
