Fixed background load/sizing issue and final heroDeathAnimation image issue.

Because the width of the new background images are different than the originals, the new background images were not long enough to load properly at the correct time. We would see a black "blip" for a moment before the new background image loaded. Tina and I scaled the new background images to the proper size to fix this issue. We also changed the loading position so that we can see more of the top of the background.

The final heroDeathAnimation image if Brad hit a contact node in the air would be of Brad Falling instead of Brad crumpled on the ground. This was because jumpMode was still activated. Before the animation, jumpMode is turned to false so this doesn't occur.
