Added ChangeImage Image subclass which has a SwapTexture function to move between different images, will proceed with further subclasses of images for later animation type stuff. Can in the future build in listeners to instances of these so that we don't fill up gameScreen with all these listeners. I don't think Core is allowed to be dependent on google.android. Right now I moved that dependency so that our android module is dependent on services.6.1.17 or whatever number it was and gradle stopped yelling at me once I changed our minimum SDK to 9. Can we deal with our login stuff in the android module?
