What cultures a theocratic Yugoslavia should or should not be accepting

[rogerburks]

When Montenegro forms Yugoslavia as a theocracy, it results in Theocratic Yugoslavia. In current code, Theocratic Yugoslavia is excluded from accepting most available cultures for Yugoslavia. As far as I know, it is limited to two: Montenegrin, and Bosniak.

The expected result of this could be that it should be an Orthodox Christian-dominated Yugoslavia. With this expectation in place, I suggest that accepted south_slavic cultures should at least include other chiefly Orthodox cultures, such as Serbian, and that if some are excluded, they should also follow religious differences.

That said, I'm not at all sure what to do about predominantly Catholic cultures, such as Croatian or Slovenian. I suppose a theocracy probably would not accept cultures that are not exactly the same religion as theirs, although I am willing to hear alternative viewpoints.

So to try to track relevant cultures for Theocratic Yugoslavia:
Accepted cultures:

• Bulgarian - predominantly Orthodox
• Montenegrin - predominantly Orthodox
• Serbian - predominantly Orthodox

Non-accepted cultures:

• Albanian - predominantly Sunni
• Bosniak - predominantly Sunni
• Croatian - predominantly Catholic
• Slovene - predominantly Catholic

Based on the above reasoning, I suggest disabling embrace_bosnians_YUG for Theocratic Yugoslavia, and enabling embrace_bulgarians_YUG. I also suggest automatically adding Serbian as accepted.
