Spices up vulpkanin [bounty] (#3425)

## About The Pull Request
Changes vulpkanin in several ways:
- Peanutbutter gives a mood buff
- Chocolate deals toxin damage while inside you
- innate hardened soles
- innate night vision
- hunger will drain twice as fast
- higher sensitivity to flashes
## Why It's Good For The Game
vulpkanin are literally human but fluffy, they don't even have lore in
the species selector (lol) also I'm being paid
