Tweak API to be somewhat better designed

Adding ability to get the painting meta-data (eg. artist, w/e) in the
previous API would have been awkward. This new setup makes it a lot
easier and places the original and blurred image endpoints in a more
sensible location. New API:

Get list of all images: `/api/image`
Get info about specific image: `/api/image/<id>`
Get original image: `/api/image/<id>/original`
Get blurred image: `/api/image/<id>/blurred`
