Issue 2778 (#3374)

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.

 ## Fixes
 
 * **[Campaign]** Fixed double counting of parked aircraft kills when DCS reports multiple kill events.
+* **[Campaign]** Fixed error where frontline units are not re-deployed when multiple control points were captured in one turn or when control points are captured "out of order" using air-assault missions.
+* **[Cheat Menu]** Re-deploy frontline units when using cheats to capture control points, so that cheats behave the same way as capturing a control point in-mission.
 * **[UI]** Naval control points (carriers, LHAs) can no longer be moved onto land.
