[Japan] Better Soryo
Fixed Manor buildings and Authority law for Soryo government.
- Manor buildings now use/provide prestige instead of influence if you have Soryo government.
- Mansion now provides maximum domain limit start from level 1 so that new vassals can immediately have 3 domains instead of waiting them to build level 2 mansion. Also adjusted the progression so that every era will have +1 max domain limit.
- Authority laws now increase vassal taxes regardless of their government just like normal feudal government.
