Subject: [PATCH] Option to disable BlockPhysicsEvent for Redstone
Not sure of any reason a plugin would need to act on a Physics event
for redstone. There is a BlockRedstoneEvent that plugins can also use
for accessing redstone activity.
Defaulting this to false will provide substantial performance improvement
by saving millions of event calls on redstone heavy servers.
