Tweaked PolicyAI Science Flavor

PolicyAI will now simply ignore Patronage when doling out science flavor
boosts instead of increasing the boost of spaceship flavor.
Operations Move Twice

PlotOperationalArmyMoves() now runs the operation move twice, in case
the operation's state changes after the first move.
Owned Territory Zones Use City Attack/Defend

Dominance zones around cities use city attack and defend
values/modifiers when calculating zone strengths.
No Food Focus when Unhappy

If an AI player's empire is unhappy, cities with food focus are set to
no focus, ones with production and growth focus are set to production
focus, and ones with gold and growth focus are set to gold focus.
