add support for video thumbnails from meta data and album artwork for audio files.

Summary:
Generally these images are better quality than those
from the Interwebz and local so let's use em!

For now using emotion_object_meta_preview_get()
as Apple stores them in this tag.

emotion_object_meta_image_get() is also available
and I've heard also it is used similarly, but
am yet to find a file that does that.
