Prototype 03 alpha v0.7

Pretty minor update. Mainly cleaning up few small bugs here and there.

  • Rewrote the color selector logic so now it works properly with Brian’s artwork.
  • Resized spawn grid so it is now properly centered.
  • Fixed rotation problem with the soldier factories, they should now face the correct way.
  • Fixed rotation on laser towers so now they match what Brian initially planned.
  • Added in Z ordering defines to make it easier to track z order of sprites.
