Slight changes to the code
Added "Gridlock" config. 4x cars and pedestrians. Great for screenshots.
Added "Omega man" config. No cars or pedestrians. Once in a while you'll find a single driving car, can't seem to stop that.
Added Normal traffic 4x peds config. I've heard that it's more stable like this.
Added backup config file.
Added "New York" 8x peds/traffic config. Very unstable, but good for screenshots.
