- Renamed `Main.tscn` to `main.tscn` to match path in `project.godot`.
- Fixed path to texture in its `.import` file; can't rename the `Textures`
folder to lowercase without changing the .glb's it seems.
- Removed temporary file.
The change to the binary `cloud.res` seems gratuitous and a Godot bug, I've
seen it on another project but couldn't figure out yet how to solve it for
good.
