Bug Fixes:
Some bonus yields from Great Works were lower than intended, fixed those.
Found and fixed a bug that could cause crashes when there were multiple rebellions in one turn.
Fixed crash in rare military AI edge case.
Tuning:
Town improvements have a maintenance cost of 1 gold.
Cargo ships cost more.
Missionaries and inquisitors cost more and have more religious strength.
Disabled civs asking you to not settle near them anymore. Borders still cause diplomatic tension.
AI buys fewer units, particularly when their gold yield per turn is negative.
Some optimizations so turns process a little faster.
