Add an "exorcization" mechanic for thralls and remove the ability to clone thralls.

If you're going to go wanting to make thralls unclonable, why not try having them drink holy water to unthrall them? This allows the people besides the chaplain to unthrall. The process wouldn't be instant and work maybe like how a counter-rev implant would work? This would make it so the strong thralls, the ones with lots of blood, would require lots of holy water to unthrall while weaker thralls would need less holy water. I don't know about counter-play though since thralls aren't allowed to hold items if I remember correctly.
