Fixed:

- Enlightenment when caves are enabled
- ETERNAL FREEZING bug

(hopefully) Fixed bug where Mym can't be heated up

Lowered Hunger requirement for heat to 70

- Added Mym producing small amount of heat when above 100 hunger
(50 degrees, small character fire, does not affect Mym directly but can heat up heat stones)
- Increased hunger rate increase relative to world temperature by a bit to offset change
- Fixed Mod select screen icon (Still need to fix 4* Lance Icon in 5* recipe and Character select portrait)
