Adding visual and descriptive board layout for Versus City Billboard (#5672)

Browse Source 
* 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.
