For the scorelog a simple numeric value may be nice (turn can be used
here). For the gamelog you need something which is space-saving and
easy to understand. I don't think that
  12,3,56,1,7,8 St. Petersburg (66, 6) founded by the Russians
achieves this. Turn can be used here. But in general this isn't this

Not if the year_to_turn function was modified by spaceshipparts (and
you don't have info about this in old savegames).

About the "awfully flexible": Keep in mind that we only have to make a
tranformation from a turn number to a string. It shouldn't be hard.

A way which alllows you to change to meaning of something. Like in
"\"" (backslash) or "foo $bar foobar" (dollar).
