Leugi's Renamed Ages

Renames the ages to Age of Agriculture, Age of Commerce and Age of Industry. The reasoning behind this is that each of the ages is designed more around a specific theming rather than around specific timeframes; so having names that don't correspond to words that we associate with certain timeframes is best (because otherwise, Khmer as Antiquity and Mughals as Modern will always feel weird) Agriculture, Commerce and Industry allow the game to have broader timeframes and focus on what is happening ingame keeping the immersion. (Because of all the texts that need to be renamed it is possible some are still weird or missing, feel free to share if there's any error or text change not applying)
