This is a small PR that corrects a math error in SharedGunSystem, causing shell casings to be "Thrown" directly downwards instead of in an actually cinematic and exciting arc. While I'm at it, I also corrected the fixture of base shell casings to favor "Bounciness", and decreased its mass to approximately 100 grams. Finally, I added a sound for when casings bounce off of walls, which wasn't present before.
