This is the nice thing about sharing your code. You go to bed, and
magically all your bugs are found when you wake up.

This is an updated version of the tester. It makes a random number
between 0 and 999,999 (not 0 and 1), and it creates a new player for
each game (I can't believe I tried reusing players). It also overrides
the player objects to account for the extra newline character that
sockets players should be getting.

Now on to the fun bit.... making that damn computer THINK.
