Any way to "dirty up" uniforms and buildings?

[mandrake]

I'm thinking, adding scratches, dents, mud etc to unit uniforms, especially the barbarians. Also making it so the cities don't look so damn CLEAN. I mean, we can imagine what, say, London looked like in the 17th century and it didn't even have a fraction of the population some of the cities in the game are supposed to have.

So, anybody know where I could start?
