The create_start_positions function isn't fair.  Players with lower ids
are more liely to be spaced farther apart.  As the loop continues, if
the players can't be put at a sufficient distance from each other the
distance is decreased.  However, this is not done retroactively.

Although this probably has no effect in almost all cases, it is very bad.
