This PR makes it so that the scale/key/chord in the Piano Roll is saved with the project. Also, while I was at it, I made it so that the zoom, vertical zoom, snap settings, quantization, and note lengths are saved too. Aaand I also decided to save the zoom and snap size in the Song Editor because why not :D However, the zoom/snap/etc are saved in the lmmsrc file, since it doesn't really make sense to save them per-project.
