Fix a funky path

-Fix a spelling error: theocratic_government -> theocracy_government

-Made it harder to convert culture while controlling the Papal states and being a theocracy, because it's normal for foreigners to be elected to the Papacy but it makes no sense for them to culture convert

-Vanilla compatibility for 1.16.0.1

-Continued targeted removal of the main causes of late-game border gore

-Bugfixes, particularly targeting the strange and random bordergore that would show up at times

-Fixed a longstanding bug involving cultural Acceptance that made AI always prefer to first convert non-accepted provinces when spreading a divergent/hybrid culture in their lands, thanks to Mozary for the report

-Logic additions (rough terrain tweaks, drylands/desert cultures bonuses in dry/desert areas nerfed as they had too much of a bonus in deserts, mountains made even harder to culture convert)
-Conversion of hybrid/divergence tweaks (more likely now)
-Better AI choices overall in county selection
