Changed bypass list to track UUIDs instead of names, in advance of changeable names in Minecraft 1.8.0+. There might be a slight delay in response now when running the /wb bypasslist command, and when running the /wb bypass command on a player who is not online. This is because the Mojang UUID lookup server must be queried in those cases. This may be handled better in a future update if/when Bukkit provides methods for caching and looking up that information.

The UUID/player name lookup code I've used is by evilmidget38, from: http://forums.bukkit.org/threads/player-name-uuid-fetcher.250926/

NOTE: if you have a bypass list saved, it will be wiped when you first run this update. The wipe will only happen once, as it is a safety precaution.
