Zach Brown 974b0afca9
Remove last bit of chunk exists region file fix 
CraftBukkit removed their implementation that caused this issue,
switching to Mojang's implementation which doesn't appear to share it. I
already removed the important bit in the last upstream merge, this is
just unused and unnecessary now. So we remove it.

Subject: [PATCH] Optimized Light Level Comparisons
Use an optimized method to test if a block position meets a desired light level.
This method benefits from returning as soon as the desired light level matches.
