Instructory comments.
Tournament, player_tourney, player, contests model tests done and
passing.
Fixed the terrible FactoryGirl problems of making matches with
preset tournaments. Also now have tests written to make sure players
playing in a tournament_match are in the same contest and tournament.
Plus other random bug fixes.
Match tournament player combination tests working and passing. One
error somewhere else. Off to refactoring the tests after I solve it.
