OPC and Reference Ships

[Guinness]

The idea is reference or example ships. OPCs would get these so we don't have to design ships on the fly, but other players could adapt and use these. (I'll figure out where to post the .sship files).

First, 2 battleships. Primarily the difference is one is Imperial units, one is Metric, hence the names. For the Metric ship, I used appropriate German guns, for the Imperial, appropriate British and American guns.
