Updates to country types difficulty modifiers:
- Added mid game crisis to marauder category to allow specifying them
- Now showing the standard npc bonuses and applying vanilla "scaled_difficulty_bonuses" to the country types that have it defined instead of a general halving on all non-crisis factions.
- End game crisis still show the actually applied values instead of 1/3 as all end game crisises have scaled_difficulty_bonuses==3.
