Create and run tournaments with no need for users to interact with any application besides Discord

[krehera]

first check if this problem still exists. If it does, try to contact Challonge on Twitter to get that ticket resolved. If they are unhelpful, consider switching to smash.gg.

create commands that enable users to:

• enter tournaments
• check in to tournaments
• enter results of their matches
• drop from tournaments
• see who their current opponent is
  ... and probably more, if you can think of something else they need to do.
