End of duel: one-click rematch and sudden death

Duels no longer drag on, and replaying against the same opponent takes a second.

Two changes for 1v1 duels.

Sudden death

At 1 min 30, both players drop to 5 hearts and no healing works any more. At 2 min 30, the player with the most health wins. No more five-minute duels spent eating golden apples.

End screen

After a duel, three choices: Rematch (if you both click within 45 seconds), New duel or Spawn.
