Add truck order queue info to vehicles panel

It would be nice if you could expose some of the truck queue order information in the vehicle panel. For example:
* Trucks are currently working on orders down to priority (or in other words, what's the highest priority truck order currently in the queue that has not yet been assigned.
* How many truck orders are currently in the queue - even better if there was a way to match this data again priority rating (e.g. number of pending orders ranked high [1-5], medium [6-10] and low [11-15]) - numbers are a suggestion only!
