Bullet Shadows Fixed, 1668 PL (for the moment)

Wow, that was worth doing! Finally fixed my flawed bullet shadows implementation I put in place back in version 9. My rank didn't change due to being in a bit of an empty area in the APS distribution, but APS increased by about 0.4, and for the moment, I'm tied for 4th in PL. However, I have a lot of battles that are very close to 50 in % Score; I could see possibly losing my lead against CassiusClay, Shadow, and Scarlet (wee! I've never beat Scarlet before!). Meanwhile, Diamond, Druss, and Tomcat continue to be quite deadly; I'd be happy to make 45% against any of them.
