Regenerate thumbnails on save
I noticed that thumbnails can get out of sync if you:
- Rotate once an image through Ctrl+R (both image and thumbnail are rotated 90 deg)
- Save through Ctrl+S (same state as before)
- Rotate again (the image is rotated 180 deg, the thumbnail is rotated 270deg (!?))
After this patch, the thumbnail is regenerated and reloaded. It does have a quirky side-effect: the new thumbnail generated by the OS does not equal the original thumbnail after a rotation, so there's a slight displacement after saving (see video)
