Replaced the separate double sided lite shader with a culling mode drop-down box. The regular Flat Lit Toon Lite shader only supports Alpha Cutout; separate Transparent and Fade shaders will be added later.

Removed the blending mode drop-down box. Added a checkbox to enable or disable Alpha Cutout.
