Duel

This bot allows you to declare a duel by typing "!duel" in chat and other people can accept said duel by responding "!duel" and after 5-15 seconds the bot will say "high noon" and the two opponents send a message. Whoever's message is first is deemed the victor and is given the role of Sheriff and the loser is labeled dead and can't declare duels for about a minute. You can withdraw from a duel by saying "!stop" or if some time passes, it will remove you from the dueling queue.
