Thermal:
* 1.0.3 features a revised thermal mechanic to better balance heating/cooling between pods and spaceplanes.
* Parts now have separate internal temperature and skin temperatures.
* Skin temperature is the temperature used for radiation and convection, as well as engine exhaust damage.
* Part internal temperature is increased by modules that generate heat and is used for part-part conduction.
* Part internal and skin temperature also conduct between each other.
*Solar panel efficiency is now calculated based on skin temperature.
* When in an atmosphere, there is a divide between the exposed (to convection) and unexposed skin temperatures.
* When not in an atmosphere, only one skin temperature is tracked; the two temperatures are unified on atmosphere exit.
* Radiative outflux and influx is tracked separately for exposed and unexposed areas of skin (since the shock temperature is much higher than ambient temperature).
