Fixes various runtimes

Runtimes created when trying to apply radiation to a mob destroyed by
monkeyizing, trying to add different components to lists of salvage,
attacking non-carbon mobs with lighters, and blending monkies in the
food processor.
Changed a Fix

Fixes monkeyVsFoodProcessor properly - blood buckets are now created with dna.
