I wanted to project a land and ocean map together, but that didn't give me filled-in oceans. Will
look at this again at some point.

Cloning an existing unit and changing its value is a fair bit faster.

Since the character creator now produces a builder object with things
like the name included, we no longer need to have a duplicate copy of
the character's name (it was needed because the name lived inside the
anonymous function, and thus wasn't accessible).
