Fairer rounds and Corebot 4.5.5 support.

• Trivia, Heads or Tails and Guess the Number give each player one answer per round, so trying every option no longer wins.
• Beating Akinator pays coins only if you turn on Akinator.Rewarded, because the player decides whether each guess was right.
• gamestats is now gamewins (gstats still works), so Corebot's own game stats commands work again.
• Slash commands always get an answer.
• Who's That Pokemon accepts plain names such as Giratina; trivia answers are shuffled fairly and show special characters properly.
• Guess the Celebrity is skipped without a Movie Database key, Akinator cleans up after itself, and counting accepts formatted numbers such as **12**.
