There are four main changes in this version.

1. Enabled painting.
2. Added doors.
3. Added windows.
4. Added foundation pillars.

While I hope it will not be noticeable, most of the meshes have been modified since the previous version. I found a process in Blender that combines polygons when it can do it without changing the shape of the mesh. That makes the meshes easier to work with in Blender and I hope it might improve performance in the game a little.

I have changed the texture for the smokestack, since I thought the previous one looked somewhat fake. I am reluctant to make changes that affect the appearance of structures people have already built, but in this case I felt some improvement was needed.

The mod does not include sloped half walls. I have never used them myself, so adding them has not been a priority.
