Major [FIXED]Head Revs that respawn as critters still count as alive

[Studenterhue]

Pretty weird it does this, because previously, as far I know, the game still considered them functionally a dead Head Rev, (even though the roundstart stats counted them as alive). So if two Head Revs had died and one was a ghost critter, the game would declare a Head of Staff victory. Same with ghostdrones and borgs.
