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.
