Added a new Project in addition of the 8 National Wonders.
This project will be useful when you will want a City in "stand by" mode.
Its production cost is huge and incrementing with game progress. I was thinking about you and me not to be annoyed every few turns if your city has very high production output.
Your city will produce a reasonnable, almost weak, bonus of 10% gold of its native production output. I really didn't want more than that, since it should be your very last alternative. Meaning a city with a solid 40 production output (around medieval average) will produce only 4 gold per turn with that project active. Im sorry but our laziness has a cost and it's better than nothing ! im sure you agree with me : D
