This PR addresses #2778 by:
- Updating the logic for how redeployment of front line units works to
handle "out of order" captures e.g. for control points A->B->C, where A
starts friendly and B, C starts as enemy-controlled, the player captures
C first, typically using air assault.
- Updating the cheat logic so that capturing CPs using cheats behaves
the same way as capturing CPs normally.
