simulation/data/civs/ contains the descriptions of all civilizations
simulation/data/auras/teambonuses/ contains the team bonuses of all civilizations
simulation/data/auras/units/catafalques/ contains the catafalque bonuses of all civilizations
simulation/data/auras/units/heroes/ contains the hero bonuses of all civilizations
However, civilization bonuses are distributed somewhat arbitrarily into separate carthaginians/, celts/, hellenes/, mauryans/, and persians/ folders
This patch groups all existing civilization bonus files into a single folder: simulation/data/technologies/civbonuses/
Also implemented a more uniform naming scheme. These changes should make things easier to maintain and allow for future additions.
