Shared tomatoes, P1 sandbox spawns, and weapons left out

- Tomato splats are kept in the match, so everyone sees everyone's
  (others' arrive in replays, which play no effects), each splatting
  with juice and a sound once.
- The sandbox's first player (solo or hosting) spawns on the arena's
  P1 mark.
- A thrown flail ball or grapple stays out when switching weapons, and
  another weapon fires while a grapple hangs on. Mines, flail balls and
  grapples go once their slot no longer holds the weapon that put them
  out (mines fizzling).
