Subject: [PATCH] Optimize NavigationListener
I believe Mojang intended to call the NavigationListener Block Update
method anytime a block is changed, but accidently added it for every
block physics event instead.
This code is massively ineffecient, and physics is so super hot, it
destroys server performance.
This patch moves the block update call to setTypeAndData instead of
on Physics.
