This is why the is_ocean macro was added. For code which only cares if
a tile is ocean or land, is_ocean can return that value, so the code
doesn't need to check if the tile if shelf, or sea, or ocean.

I like the Civ3 feature of having triremes be safe on shelf, instead
of safe when adjacent to land. I think we should definitely implement this.
