AI + cleanup

AI can now change policy through an on_monthly. Their current diplomatic agenda/strategy is usually the deciding factor, with the exception of true neutrality (requires the modifier/status) and isolationism (which requires the trade law of the same name).

Also re-configured the GLOBAL so it only goes through each country once. Small performance gain on starting the game, I assume :s
Since this GLOBAL is fired immediately before the player takes control, even player countries get a relatively correct law! Just in case, the restricting variable is removed after firing in the GLOBAL, so players can select their own.
