New Key Box option available for all Exacta, Trifecta, and Superfecta wagers

A 'Key Box' bet includes all possible combinations of selected 'key' horse(s) when combined with other 'non-key' horses in a box bet.

For Example, a $1 Trifecta Key Box: 1/2,3,4 This Key Box wager would cost $18. It covers eighteen possible combinations-

1/2,3,4/2,3,4 (6 combinations with the key horse finishing first) 2,3,4/1/2,3,4 (6 combinations with the key horse finishing second) 2,3,4/2,3,4/1 (6 combinations with the key horse finishing third)

To win a 'Key Box' bet, each "key" horse must finish in one of the wager positions (eg. 1st, 2nd, or 3rd in a trifecta) AND "non-key" horses must finish in the other remaining positions of the wager.
