This adds a button to units carrying resources to return their resources to the closest viable dropsite or abort any other current order and attack-move the location specified. (The ctrl-Q only attack units-hotkey should also work.)
Cf. this topic.
It would be nice:
- to have a proper icon for this;
- to remember the work the unit was doing so "back-to-work" can be called.
This is good for lazy people like me who want to react to an enemy attack with all units but without their resources. If units without resources are also selected, they stop current orders and attack-move directly.
