Adding visual and descriptive board layout for Versus City Billboard (#5672)
* Adding visual and descriptive board layout for Versus City Billboard Similar data is provided for other Sega boards. I tried to be as descriptive as I could. * Update segabill.cpp * Adding "thanks-to" for board layout and documentation credit. Originally credited into "copyright" when no contribution was applicable to copyright. Name credited to "thanks-to" instead.
