succumb calls death() now, which does set stat to DEAD, I figured it made more sense to throw it there and not in ghost.

Previously if someone succumbed there'd be a weird few moments where they'd be have fatal damage and be technically dead  but could accidentally go comatose because death() wouldn't be called until the next health check, so this actually fixes that problem. 

I did bugtest this code of course, as much as you can really bug test 3 lines of code
