New turf proc: assume_gas(). Maps to air.adjust_gas_temp(). Lots of optimizations to processing, fire, lighting, HasEntered() and more. Zones now process all fire data and existance in one go, fire objects only handle spreading. Most code has been ported straight so some of it mightn't be ideally structured for the new gas_mixtures.
