Bukkit

R1-BETA

• fixed a bug where the hfillmap[i][xyz] could be indexed with a negative Y component (below zero) which would cause the thread to throw an exception and stop working on the worlds assigned to it and lock up the main bukkit thread

R2-BETA

• fixed bug where configuration option for regeneration threshold was not properly used in the code and all chunks that were not protected would be regenerated despite how much damage was done to them
