GameResult now holds game type which is either Match or Set game. The description for game result now includes type of the game which is used to distinguish what type of game has been played for given scores.  For the SetGameViewController we now initialize GameResult with game type = Set game. The original CardGameViewController uses default GameResult instance which has game type = Match by default.
Match/Set game score results now printed separately on the Scores tab - first all Match games - then all Set games.
Added new Settings tab which now holds "Reset All Scores" button. Scores tab now has more room to display the scores history.
