Yay for recoil and cheesy additive lighting!

Today I added a little bit of production value to Tankz. I've paved the way for weapon customization, and added a 'recoil' effect on the main cannon. It looks pretty cool. I've also added some non-HLSL lighting for the time being. Once I can figure it out, it will be slick looking multiply-style lighting(maybe even dynamic shadows!), but for now its just cheesy additive. Oh well. All in time!
