Fix issues with rP25077
Issues from rP25077 fixed:
- The AI config page does not work
- Player Color/Civ/Team did not reset when switching out of Scenario, which locked the setting
- Player color had weird issues with resetting when changing map too.
- Pop Cap could not be changed.
- Explored/Revealed were swapped in the game description (this was actually fixed at some point in the original diff then reverted).
