Updates the proto definition to add a preview description and date field. Date and description metadata from fetched content will be sent over the wire. We can't render it locally yet, but at least this will allow supporting recipients to display the content. Also, made some minor changes to HTMLMetadata to better handle article publish/modified date tags.
