- Updated to include Update 1.10's cultures

- Made 'on_game_started_after_lobby' actually trigger the correct on_action

Utilized the new on_action, on_game_started_after_lobby, to add the culture checks to the countries.

- Updated to include the missing Szekler culture.

- Updated to include Update 1.8's cultures

- Updated to include Update 1.7's cultures

- The check for the primary cultures has now also been bumped-up from every half a year in-game to every year in-game for performance reasons. I found out about the Script Profiler recently and this mod uses the most amount of performance in the script, so these were necessary changes to improve performance.

- Bumped up the clean-up of the primary culture trackers from once every 6 in-game months to once every in-game year due to performance reasons.

- Optimized the mod's code

- Added a warning to this mod's Workshop page against using this with Total Conversions/Alternate History mods
