Medieval Expansion 1.20 Update

<p>This is a slight edit of Elocrypt's Medieval Expansion patch to 1.20 that just removes Waterwheel damage. thats it. nothing else has been changed, cows are still in, waterwheel output is the same, just removed the damage per tick<br /><br />After testing the damage is still there, but its noticeably slower, will continue testing till its fully removed</p>
