Box Flow Fitness Game modes

Adding multiple games modes for 2 players.

First, where one player has a freestyle mode for a set time, then the other player has to match the other players combo (Like a game of horse for basketball.)

Next would be a training gym function to pick out training options, such as: dodging, footwork, speed bag, or hanging bag.

Lastly, a boxing mode against a computer to work on reflexes and blocks, and punches.
