More specifically, whenever the player dies and we need to reset the
screen, wait for items to fall in the same way as we do for explosions
to disappear.
This also brought with it some other changes like removing sprite reset

This now only supports the appearance of shuttle parts and the fact that
the player can collect them at a very specific order and drop them so to
stack up the final shuttle.
This is of course just the skeleton and there's a bunch of TODO's left.

This is a bit contrary to the original game, where each player would get
its own "Game over" event.

This allows for explosions to run after making the player to disappear,
and it re-runs the entering scene timer.
