Add Skins as a side game for Bingo Bango Bongo

Players can now opt into a Skins side game when creating a BBB round.
The side game uses the same skins settings (carryover, net/gross, skin
value, double back nine). The scorecard gains a third Skins tab during
play and on the summary; the BBB leaderboard continues to rank by BBB
points.
