Added a friendly Horror Zoo

I added a friendly Horror Zoo with seven nonhostile Techno Horror displays. It gives the different machine bodies a place to be inspected together without starting a fight.

The Horrors also have a revised gunmetal finish. Their visible displays participate in streamed contacts, while those derived display objects stay out of campaign saves. This is a model-viewing space, separate from their hostile encounters in the field.
