Improve file attachment comments in review emails.

Comments for file attachments in review emails were kind of crummy. They'd show
either the caption or the filename (unlike the web UI, which showed both). They
linked to the download URL, even when there was a review UI. And finally, they
wouldn't show comment thumbnails.
Set up a review and a reply and checked out the preview-email URLs.
