new traitor objective: personnel extraction

[Naximous]

How about instead of extracting personnel, you have to extract one of the pets. Take them to a certain part of the ship, use a certain traitor only thing on them and they're teleported away. Even better, Heisenbee, Dr. Acula et al aren't going to commit suicide on you.

This means that all animals are going to be killed 'n gibbed at round start.
