External attachments

Replace the external_url functionality in Publications and Consultations with a new ExternalAttachment type. This displays along with the other attachments (rather than a separate 'held on another website' link) and allows editors to edit the title and reorder them. The data migration creates external attachments in the first position.
I missed mentioning ISBN in the previous comment, but that was followed by "and so on, and so on..", and in other places he's used the phrase "all the metadata..". you're right in validating with the content editors. i think, we should ask them to come up with a list of fields that make sense for a external attachment, which would be a very useful exercise.
