made closest stars a bit further away

made scrolling adjustments happen even when you're dead etc (dying also doesn't reset shipx and shipy. Just shipdx and shipdy. The scrolling adjustments get the x and y straightened out durring DEAD_PAUSE)

x scrolling tries to get you one third of the way in from the left, instead of in the center

tried to make explosion center keep moving (not slow down as the ship does). It's much safer now, but still doesn't look like it matches with the graphics correctly.

strengthened the blast a bit and got rid of the silly thing where it only effects slow moving rocks at the end
