Revolution game mode fixes:

Station-heads who are monkied now count as 'dead' for round completion.
- This previously applied to revheads but not station heads.

Changed get_all/living_heads to pull from the mob list instead of the player list.
- It was causing players to get skipped by the check-antag verb admins have if they were disconnected.

Runtime fix by Erro for:
runtime error: Cannot execute null.show inv().
