Genetic downward spiral/doc

Notes

• This prevents you from gaining any good mutations, ever.
• The rate of mutation is the same as Genetic Chaos. Does not stack with Genetically Unstable.
• All non-targeted mutations are random, instead of being weighted toward the category you have the most mutations in.
• Intended for challenge runs. The disadvantage is crippling and not worth the points earned, but at least you won't need to pick any more bad traits!
