Slopes now have visible sides. The texture is visible and the lighting is okay.
I only did the side faces because the front face will rest against a block almost always, at least until we can construct slopes and break blocks.
The only problem is the UV coordinates. Some line up pretty well but other sides show the texture in the wrong direction, leading to a distorted view. Still, it's not very noticeable so it will do for now.
Fixes #165
