Support for showing tournaments

[axc]

• Support running many matches in a row (matches between different teams), each of which consists of up to 3 games
• Possibly include a splash screen in between games / matches that show
  • Who won and how
  • Current match score
  • Team names and avatars?
  • Bonus: additional headlines like "Top 8" or "Losers bracket round 4b" and stuff like that
• Should be able to resume from where you last left off in the matches list, in the case that things crash
• Should have a good place for us to the webcam when we stream
• Some way to interact with the website to show live tournament results. The previous tournament viewer also updated a row in the database whenever a match was done, which would make the completed match visible on the website's tournament results. There are probably a number of ways to do this, some of which might involve changes to the website.
• Idea: additionally show the bullet and victory points as a bar instead of only as a raw number.
• Other things?
