Title: Support for the image/pjpeg MIME type

Simple change to AFImageRequestOperation so it accepts the image/pjpeg MIME type as a valid image type.

As far as I know, image/pjpeg is used by Internet Explorer only, for progressive JPEG pictures. It might not be part of the MIME standard. Progressive JPEGs are supported by UIImage at least under iOS 6 and 5.
