Pressure and Humidity now a factor in body temperature
Rainy weather maxes humidity, cars are considered in wind
Body temp scale set to -100 to +100
Cached weatherGen
Frostbite refactor - it is now independant of body warmth, for better or for worse
Fixed a silly copy paste error in frostbite code
Words are used instead of numbers to describe wind and humidity to UI
Fixed UI inconsistency with the amount of warmth the player was gaining or losing
Added frostbite recovery disease
New frostbite system, again. More robust, more better
Consider clothing in frostbite calculations
Fixed copy paste errors
WIP

There's another handgun. Still needs the spawns, but committing to test

Being wet can drop felt temps by up to 20 degrees for frostbite calculations
Frostbite does not occur in low risk temperatures, only frostnip
