Add option to auto-rotate image

Some devices save the image data in one orientation, but add EXIF data indicating the true orientation of the image. An option to automatically apply this would be handy, so that one might do something like -o auto -x 800x600 -e

You could use jhead -autorot <JPG> alongside imgp in your workflow
