Truck Cargo type prioritization

For the pickup and large trucks, add the ability to set the type of cargo a given vehicle should prioritize (loose, flat/packaged, or liquid). I've run into many issues where my "small" trucks are running around moving and dumping mining spoils rather than moving factory items to the places that need them (when they are the only ones that can carry them). Being able to "force" small trucks to prioritize factory cargo would help immensely in the mid term with long range factory logistics.
This will eventually be resolved with massive conveyor networks, which I'm working towards, but still a ways off from having filled in sufficient terrain to allow for "non-ridiculous" layouts.

I'd love to see this added in such a way that we could select multiple items to be moved by a truck. In such a case the priority would be the order the items are added in. Also add an option for "anything else" to be hauled. So you could add, Copper, Rubber, Electronics, Anything Else.
The truck would look for jobs that involve those items, in that order.
