Preserve Metadata when resizing JPEG images

Preserve Metadata when resizing JPEG images:
One thing that Sandvox does is to make resized copies of image files. There are often a lot of useful metadata in a JPEG file, so I decided that it would be a good idea to preserve these as much as possible if scaling down a JPEG file to another size. Many but not all of these are supported by NSImage, so it’s not hard to extract from the original image and put in the other.
Good things to keep track of for later
