Improvements to data viewer embed

[rgrp]

• Decent powered by icon for the Embed for the DataHub?? (make this text customizable and allow html ...)
  • Current icon and text looks really bad
• Embed link uses uuid rather than dataset name (this goes to perma-url question ...)
• Data viewer embed url includes all the resource info (not needed -- just url and backend info ...)
• Embed extension urls do not respect original domain but instead use site_url (I'm guessing). E.g. datahub.io domain ends up with links to embed on thedatahub.org

Suggest Sam might be able to provide you the icon

Questions for client team:

1. Did you have anything in mind for improving the "Powered by CKAN" text and icon? I'll sort out the vertical alignment of the text and icon; and see if Sam has a better icon.

2. The branded section itself is already customizable by a snippet (​https://github.com/okfn/ckan/blob/master/ckan/templates/snippets/data-viewer-embed-branded-link.html). Is that enough? Or are you asking for something else?

3. Personally I think the URI should use the resource uuid, and not name. And from recent discussions on ckan-dev, I think the consensus is the same. How important is this for you? Perhaps it's something that could be overriden in the datahub extension.
