Jet

The Jet is a type of chip that can be programmed to act like a rocket. It is commonly used in planes, and sometimes even boats. Some cars use it as a boost mechanism. It can be programmed to act as an air balloon, and also as a hydrogen balloon.

If a jet is on option=0, it can be programmed to eject smoke, at increasing levels 0 to 4.

Additional notes:
 * 1 power = 1/6 newton
 * Balloons are treated as jets with the same output as normal jets, only that their thrust is always upwards (+Y in global frame).
 * Hydrogen balloons (option=1) work in both air and water, while air balloons (option=2) work in water only.
 * Jets with option=3 or above appear with jets with no exhaust flame on your local screen, but they appear as balloons to others while playing online.
 * Balloons have air friction, which is independent of their orientation.
