Improved texture sampling to allow for soft/dithered texture edges. #20

Updated common.hlsl::IsHitTransparent to allow for soft textures edges by dithering the alpha channel. Existing wall rendering looks the same and performance is identical. Note the hard edge in the first screen and the updated soft/dithered edge in the second.
