Sheep eating grass causes no block update

When sheep eat grass the block changes to dirt (so a new block ID) but it doesn't cause a block update.

BUT when the grass dies from it being obstructed from enough light it DOES create a block update. So please change this so it also generates an update when sheep eat it.

This is NOT the same as the redstone lamp/fence gate block update issue so don't remove this one for that, thank you.
