feature 2040: to finish the "automatic rotation" feature, I had configuration

setting. I choose to have it in the configuration file and not in the web
interface because it is a bit too technical and useful only in very specific
cases (when buggy software performed a rotation before without updating the
EXIF "orientation" tag)
