Determines the default cargo type of an engine.
Usually a valid cargo is returned, even though the vehicle has zero capacity, and can therefore not carry anything. But the cargotype is still used for livery selection etc..
Vehicles with CT_INVALID as default cargo are usually not available, but it can appear as default cargo of articulated parts.
