Bukkit

DO NOT USE THIS VERSION, PLEASE WAIT FOR 0.9.7

• fix for multiple worlds without multiverse (ticket 18)
• fix for loading old inventorie files on 1.1-R4 (oh i hate this damn fuing bug of 1.1-R4)
• fix for projectiles (snowballs)

• blocking all signs and chests isn't a good solution, but the minecraft-server lags the possibilities to intercept inventory-modifying for now
• breaking needed blocks lets drop attached ladders/doors/etc.
