Minecraft clone in Python tutorial EP4: Making the scene 3D

Important notice: there's actually a small error in the matrix multiplication that was brought to my attention by @randy#2400 on my Discord server, and which has already been fixed on the GitHub repository. Basically, the projection matrix needs to be multiplied by the modelview matrix, not the other way around. More details here: https://github.com/obiwac/python-minecraft-clone/issues/16
