Reverse order

[krtaylor]

It would be very helpful to have the ability to enter a "Reverse" order in a train's orders list, in the normal list with the usual destinations and waypoints, to force it to turn around. I would very much like to be able to use this when the train has arrived at its destination, and instead of continuing along the mainline it's supposed to turn back and return in the direction from which it came. Using nearby waypoints helps but doesn't guarantee that the train will properly turn around; a command to force the turnaround would be really helpful in preventing snarls.
