Make the map a little bit more lively

[Naokaukodem]

Just saying, but by the time we could have people on the map. Particularly people traveling through roads. First they would be on feet, and then suddenly when the wheel is researched they have carts and mules or something. They would wait in the edge of roads when a military unit pass through. They even could have their icons. Ok, they could be just merchants, but in that case we could need a lot more of those. Nah, mere travelers should be in to. If the zoom allows it, we should be able to see people in cities too. And finally, nomadic people in the wild making their own lives. (maybe we should be able to follow their tracks and those of other civs units in neutral territory with a unit with the scout promotion or just scouts - we could also follow tracks of animals too, to gain bonus food if hunted, but animals should move in that case)
