Bukkit

- Updated to last recommended build. - Added option to disable redstone devices.

The protocoll uses some characters to split up arguments and identifiers.
I will work on that, but until then try not to use the following characters in the global chat: '[', ']', '°', '~'
I tried to chose characters which are not often used.
If you use them your server won't explode :P, but it might cause chat messages to not be displayed properly.
