Ah you already did it, nice on Ruprecht.
You can compare files to one another using a program called winmerge, its free to download. All you do is open it and in the first option open the vanilla file and in the second option open the edited file and then click ok and it will highlight all edited lines of code and tell you what has changed. This will help teach you how to mod things in RTW and other games more easily as you will see the effects from playing with the modded version and by seeing the way the code was changed you can see how the code was edited.
I've been modding Age Of Pirates 2 City Of Abbandened Ships with a few guy's, the full uncompressed game is something like 4.5GB's with our work added its over 13GB's now. Most of that is new textures, ships, characters etc etc, but the amount of work we have put into that game its almost like a new game. Pirates Of The Carabbean (i never worked on it and is not part of the movie POTC at all) the team working on that have made that almost a new game but with the developers giving us the source code for COAS we hope to make the game even greater.
Anyway back on topic, i could manage with the squalor as it was but after playing as much as i have it soon gets annoying and to be honest in medevil 1 or 2 the barracks did give you a law bonus from what i have read so i can't understand why that would be changed if squalor would become a bigger problem than it needed to be. The way this game has been coded although not too hard to understand can be confussing at first, i want to get a new map into the game, i already got one map working but i like the one from SPQR however because TWC was down i couldn't ask LT if it was ok to use his campaign map for my own project, so i will send him a PM in a few minutes to see if its ok or not.
Again good work bud.
