 - Fixed retaliating simple animals acting weird and added some minor improvements. They should act better to mechs.
 - Decreased the amount of possible chickens you can get from the crate.

Runtime fixes for building computers with mech boards or an AI core circuit. I changed their board_type to "other" instead of the default one, "computer"

Viruses don't spread via blood/vomit pools any longer.

Reasoning in this thread

If people really want to make viruses garbage collected instead then whatever I guess, but I still think not having those 500 viruses at all is better than them being spawned, processing, then being garbage collected (or deleted after all if anyone cleans the decals).

Should probably look into lessening the vomit rate as well.
