New commit:
- new difficulty levels: Heir, Regent, Monarch, Emperor, Paragon
- Heir equals Viceroy
- Regent equivalent to old Monarch
- Emperor equals old Emperor
- Regent has slightly higher unit upkeep and inflation rate compared to old Monarch
- Monarch and Paragon are slightly harder than Regent and Emperor respectively, featuring higher research costs and higher AI unit and wonder production
Yes, I renamed old Monarch to Regent and called the new level Monarch. I am allowed to break my own rules, it's one of my hypocrite powers.
