Game details for team events

When a Sports team or Trivia team Space is hosting, the composer adds a few lines for game day:

• Opponent: who you're playing. It's set on each date, since every game in a season has its own. Trivia teams don't get this one, since a room of teams plays at once.
• Players needed: the fewest you need to play. If fewer are going on game day, the players who haven't answered get asked, and you'll hear how many you're short.
• Arrive early: how many minutes before the start, for warm-ups and check-in.

Guests see it on the event under Game: the opponent, how many are still needed to play, and Arrive by with the time.
