Couple otie tweaks.

-Makes sec otie start with safe belly upon eating any human, not just crime threat ones. (retaliation against lawful crew members etc.)
-Brings back the grab-unfriend thing. The friend thing literally only tells it who to follow around and currently there is no other "stay" command to get it off your tail without just passing it for someone else's trouble.
