Bukkit

There are so many changes in this one that I don't feel like copying them out right now. You can get an idea by looking at the revision history, though that'll be a little cluttered by refactoring and similar changes which don't really affect functionality.

Some of the below may still be the case. There may be other issues. This version has not been extensively tested.

• I'm not entirely sure if "playerlist.show-invisible" works, or if the "general.invisible-info" permission works.
• Some of the help entries are incomplete (notably for /misc.mobspawn and /teleport.go). I can't figure out why this is, since the info is being added but Bukkit seems to be ignoring it.
• Potion data is a bit strange; if you give a no-effect potion it'll tend to think it's called "null" for some reason.
• To get help, you need to use the full name of the command including the category, so "inven.give", "chat.tell", "misc.time", "teleport.go", and so forth. This shouldn't be a major problem since the /help command lists them like this anyway.
• Aliases are missing from the help output.
