Unit Movement Confirmation

It would be cool if there was an option to cycle through all units that are not asleep. Including those that have an active order (movement that takes more than one turn or exploration) but still have movement points. This way I would be able to watch all active units I have but at the same time I'm not going to forget the plans I had for any given unit.

No files, tests, or entry points are named in the issue. Start by locating the unit-selection and movement-confirmation UI logic, then trace how sleeping units and units with active orders are filtered. Done means an option cycles through every non-sleeping unit with movement points, including units continuing multi-turn movement or exploration orders.
