Revert "PB+SWMH changes reverted"

This reverts commit ccacd3521dd067eb5fe7f308bf3eeb155eb4902f.
Fixed minor adjacency issues
Warrior cult galley buff

The Warrior Cult building now gives 2 galleys
Dejure Iberia event tweak

(PB+SWMH) If Aragon hasn't been expanded when Castille's dejure area is
expanded to Murcia, expansion is applied, giving Aragon Valencia and
Mallorca dejure
Raiding buff

Reduced the amount of gold protected from raids by fort level by 25%
Mongol tweaks

The Ilkhanate spawns further south, attacking the kingdom of Persia
rather than Khiva. This should lead to them expanding in the correct
direction more often
Mongol event forces now take 10% of normal attrition rather than no
attrition
Coastal county conquest check
Claim pushing fix

Fixed AI emperors being able to push the claims of people who they're
not either married to or close relatives of

Expanded on the description for the "is war possible?" decision for
Pagan subjugation
Lower building cost

Removed the 50% increase to all building costs (added in vanilla 1.10)

Fixed some issues with navigable rivers, including the Danube being
navigable by anyone
Imprisonment event fix

Fixed an issue where imprisonment events would sometimes fire when they
shouldn't
Genetics

There is now a low chance of inheriting genetic traits from one's
grandparents upon birth. For most genetic traits you get a 5% chance of

(867 start) The Seljuks no longer start so ridiculously far north, so
they're far less likely to expand into the Steppe
Steppe building fix

Fixed the Steppe buildings not having maintenance costs nor giving
retinue cap
Papal Investiture excommunication fix

Fixed the Pope being able to excommunicate you for refusing Papal
Investiture after you've appointed an anti-pope or after his own death
Mongol logic/flavor

The Mongols can now convert to Reformed Tengri if they manage to get
ahold of provinces with the religion
If the leaders of the Golden Horde and the Ilkhanate are the same
religion, Timur will be the same religion as them rather than Shia
Tournament event fix

Commented out the event that clears tournaments that go on for long, as
it should no longer be needed

Fixed liberation revolts sometimes leading to kingdoms with no crown
