Topping bins to replace game instructions on screen

[Wesley Chan]

Instead of the ugly ass text saying what buttons to press, we want labeled bins rendered above the pizza that have the toppings in them, as well as labels to show what key to press to get that topping. To do this, create a toppingBin object that instantiates 4 prefabs on Start(), equidistant from one another (and some distance from the sides of the screen). Then, populate the bins by instantiating a bunch of the corresponding topping on top of the object (again, on Start()).

Make sure the distances are scaled to the screen size. Check with Eva to see if she has the screen sizing done (not sure if she's storing a global variable or something). If you can't get ahold of her, just spawn them with absolute distances for now, we can get Eva to fix it later.

Use some ugly placeholder sprite (I'm talking Microsoft paint level) for the bins. We'll get good sprites when we really bang out the graphics.

The bins should look full of toppings, if you know what I mean.

Oh and don't forget to create a new branch for this thanks
