This patch is part of the work to differentiate the civilization from the Romans.
Adds a new bonus civ in search to differentiate the Romans and bring about some kind of gameplay change.
The patch gives +2 population bonus for military/economy structures, and can train women in houses without needing to research tech.
This is to represent the population density of ancient Rome.
I believe this can bring some interesting changes to the gameplay of the Romans, especially at the beginning of the game.
