- 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

- Turns out this mod was breaking every single country formation event, so this update is to fix this major error. Sorry about this huge oversight on my part.

- Decreased the time for the checks to clean up variables used to track cultures from once per in-game year to once every half in-game year. These checks are to remove the variables if a Primary Culture gets removed via events.

Did you know that as long as your subject's capital is in either the Rhine, North Germany, or South Germany region it can be picked to become the Confederation of the Rhine? And I mean any subject?

Unfortunately they will only have their old Primary Cultures and not have North and South German as Primary Cultures, so this update rectifies it.
