Use random() instead of rand(), so we get something like random 

numbers out.

This changes the "tournament codes"; that is, the same code will give
you a different game now from what it used to. (This is because the
codes are basically random seeds.) I really really doubt anyone cares
about this, especially since the tournament feature appears to be
undocumented.
