[GREENFOOT-171] Set a scenarios maximum speed
Often I need to set the speedometer to maximum in case someone is using a low end PC, however if they use a high end PC then the game is way too fast. So if you could set a maximum frame rate which the speedometer will not go over, say for example you set it to 60fps, then even when the speed is set to maximum it won't run faster then that.
