miod 3efbeaf828 A potpourri of changes: 
- do not mention a mail being sent when hiscore is broken, this feature is
  disabled.
- when a player dies, reset eater position. Also pick startup position closer
  to the MSDOS version of the game.
- use {s,}random instead of {s,}rand.

ok deanna@ for my yearly ports commit.
