Enable opt-out from max image resolution; fix EXIF based auto rotation

[Petr Nejedly]

SOme devices could have <restrictImageResolution>false</..> (xbox) so that we don't have to transcode if the resolution is higher.

Also EXIF is lost when we resize/rotate image and therefore automatic rotation will not work properly -> When we resize we should always also rotate (if found in EXIF), no matter the config.
