Spaceframe expansion

[Felderburg]

As seen in #60, not all ships are created equal. It might be worth considering a way to include non-traditional spaceframes, such as the cetacean ops mentioned and other civilian craft. (Perhaps a way to tie in #8 as well?)

Part of a "spaceframe expansion" could also include shuttles, although given that they generally have set stats available in books, it perhaps would be an overreach. But for certain ships, such as the Danube, it might be nice to have a reference, or perhaps a list of what page to find their stats on.

So maybe this "expansion" just ends up being a reference list of what books to find non-player ships in, which I suppose is alright too. Or maybe it becomes an entirely separate "Utopia Planitia" section, depending on what that book ends up being.
