Title: Temperature 111

The first part of the temperature implementation - terrain with temperature
* another terrain layer with values interpreted as temperatures
* default temperature depending on (physical) terrain height
* lava heats the terrain, water cools
* change solid terrain to lava when temperature is too high
* burn the green stuff
