 -we want to see how many boost are available, so we  add a display for
it to the GUI
-show the distance traveled so far as well.
-Add two variables to GUIManager for these new objects and assign them.
- = Boosts and distance.
-We add two static methods to GUIManager which Runner can use to notify
the GUI of changes to its distance traveled and boost count.
- let Runner call those methods whenever its distance or amount of
boosts changes.
