Carpenter's block (Port)

0.3.3

• Smooth lighting now works on all Carpenter's blocks (blocks, slabs, stairs, slopes, collapsible blocks, side covers, chisel designs). Shadows on block faces are smoothly blended and use ambient occlusion, like vanilla blocks, instead of hard per-face shading.
• With "Smooth Lighting" turned off in video settings, blocks keep the old flat lighting.
