Promote Culture changes to AI
Introduces some changes to AI:
– Independent AI rulers can now Promote Culture in their capital.
– Zeal and negative compassion drives rulers to Promote Culture.
– Some traditions will make the AI less or more likely to Promote Culture. (Xenophile, Culture Blending, etc.)
Promote Culture will happen more often, but border-gore will be limited due to culture promotion being spread along the cultural borders. If there are no borders, indepedent realms start with the capital and spread from there.
