Horserace

The horse race minigame includes a horse race with 4 horses (one horse for every player) which randomly move forward.

Current implementation of the Game Loop:

1. The horse race screen starts
2. It is randomly determined what horse will make the next move forward (only single moves)
3. The selected horse moves forward
4. Step 2 to 3 are repeated till one of the horses has moved the defined steps necessary to win the race
5. After a winning horse has been determined a screen appears which shows the winning horse/player
6. The horse race screen is disposed and the players return to the game screen
