Updated for new version of Real Strategy
Added city states starting walls back for now until I find a better solution
Added option to remove the difficulty combat bonus

Changed the way the production, gold and faith modifier gets applied to make the military of science and culture civs more equal:
Removed 5% production, gold and faith bonus per difficulty and era
Added 1% production, gold and faith bonus per difficulty and civic

Added an option remove the additional tourism modifier that the AI gets on Deity and above

Small tourism nerf and some small improvements

Fixed compatibility with missing DLC

Moved free ranged units upon founding/conquering a city to Pro difficulty and above

"Fixed" bugged difficulty combat bonus of city states that emerge from barbarian outposts with barbarian clans mode (they still always get the highest bonus possible of +6 regardless of difficulty, but at least its not 4 million anymore)
Small tourism adjustments
Lots of smaller adjustments to Real Strategy

Added option back for bonus starting warriors
Added additional science/culture until medieval era when using the option that removes bonus starting settlers
Added back the free ranged unit on founding/conquering a city

Changes to strategy evaluations when using Real Strategy to reduce variance in AI perfomance (AI (especially domination civs) should fall less behind other AI; a bit more equal overall AI perfomance)

Fixed a mistake from last update where all difficulties got the extra boosts from Insane (big oops)

Updated for the latest Real Strategy version

Changed when the AI gets bonus amenities (no longer scales with game era, but with player era instead and not at every era)

Removed bonus science modifier on Insane, added bonus eurekas/inspirations on Insane (should overall be harder)

Removed difficulty combat bonus from city states when using barbarian clans mode because it caused bugs
Minor changes to city state military

Fixed tourism being too low without BBG.

Simplified combat strenght modifiers: No more era or game speed specific combat bonus, only default combat modifier
Added military unit production modifier for different game speeds instead (-20% online speed, +40% marathon speed)
Removed city state bonus starting units (levying felt too strong early and they still survive well enough with the buffs)
Added new leaders to Real Strategy

Cleaned up the mod code to make it hopefully easier to modify/understand for others.
