Subject: [PATCH] Fix Player Banning

This issue stems from the fact that Bukkit's API only allows a UUID to be banned, but Minecraft requires both a UUID and name. To fix this we modify the code to require a UUID or a name, or both. The correct fix would be expanding the API to be able to provide a name, however this would require plugin changes.
