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.

Station Roles are picked before Syndie Roles unless it is nuke or wizard
People should no longer spawn in space because they did not get a job.
Heads and such should no longer get a role they should not have.
Rounds now have a minimum number of players required for it to start up.
Also the atmos pipes should stop exploding all over the place.
