Adding happiness bonuses to buildings?

[fierywokbar]

Hey folks. Sorry if this is in the wrong place, figured I'd get more traffic in here than in the mod section.

Basically, I'm really sick of playing RTW/BI as a barb faction and finding that I have to constantly mini-manage my cities so they won't revolt. Despite buildings Churches and walls [to increase public order], and slowly destroying culture penalties through building on top of previous faction's buildings, I have to stack some cities full of troops so they don't revolt. Obviously that takes a big chunk out of my income.

What I'd like to find out is how to add public order bonuses to barracks, just like in M2TW. Additionally, I'd also like to find out how to INCREASE the public order bonuses that city centers provide.

Again, look at this or this.
