Bukkit

• Removed some biomes that seem to not be in some random version of Bukkit (should be no more crashing).
• Gone back to Notch style biome code to try and fix deserts (that didn't work)

Requires build 1774 or higher !

• You may see some slimes...
• Desert biomes will still not have sand in them. This is due to a bug with Bukkit as far as I can tell, it seems that the biomes calculated when the world is generated are not the same as when it is populated. Weird !
