Implement Image API

[tisto]

{
    contentType
    size
    data/download
    filename
    scale: {
        'mini': {
            href: ...
            width: 400,
            height: 200,
        }
    }
}

Image fields currently get serialized as a mapping of scale_name: download_url (see docs).

I would propose the following serialization format instead:

{
  "@id": "http://nohost/plone/my-image",
  "@type": "Image",
  "title": "My Image",
  "...": "...",
  "image": {
    "filename": "image.png",
    "content-type": "image/png",
    "size": 1185,
    "download": "http://nohost/plone/my-image/@@images/image",
    "scales": {
      "icon": "http://nohost/plone/my-image/@@images/image/icon",
      "large": "http://nohost/plone/my-image/@@images/image/large",
      "listing": "http://nohost/plone/my-image/@@images/image/listing",
      "mini": "http://nohost/plone/my-image/@@images/image/mini",
      "original": "http://nohost/plone/my-image/@@images/image",
      "preview": "http://nohost/plone/my-image/@@images/image/preview",
      "thumb": "http://nohost/plone/my-image/@@images/image/thumb",
      "tile": "http://nohost/plone/my-image/@@images/image/tile"
    }
  }
}

This doesn't include the dimensions for each scale as in your initial suggestion, but including those would make the response really rather bulky. I don't feel strongly about this, but I probably wouldn't include those until we have framing in place and a client can request to have them omitted.
