new chngeling power

[Daeren]

Implement one of Cogs's favorite gimmicks and make it so surgical removal of the headspider means it jumps back out still alive and kicking and infects anyone dumb enough to be nearby. It leads to giant scrambling chains of people getting infected, operated on, and then their surgeon gets jumped in a never-ending chain until someone kills the headspider or a medical cyborg steps in to do it.
