Team dropping out of the tournament

[teijo]

Adding this just as a note to self, or anyone interested:

A team forfeiting a match or tournament is a separate problem from not being in the tournament to begin with (i.e. what #8 is about). The question is, if a forfeit should be indicated in some way instead of giving e.g. 1-0 score for the team that got default win. Also, if a team advances in a double elimination, and then forfeits the whole tournament, instead of giving BYE in the possible winner bracket, the team would need to BYE automatically also in loser bracket.

Additional use case to test from #125: both teams quit in same match.
