Custom difficulty levels!

Give us the ability to tweak the difficulty level of the game in various independant ways, e.g. AI hostility to the player, AI aggressiveness levels in general, AI economic bonuses, AI unrest bonuses, AI troop morale/accuracy/etc bonuses. etc etc.

Obviously have Easy/Medium/Hard/V.Hard presets as before, but at least give us the option of ramping up the difficulty (M2TW is just too easy to win, even on VH/VH) in a way that suits us individually as players.
