Issue #3: Tweaked content type and view settings for chapel messages

I added the "scripture reference" field to the chapel message content
type, and adjusted the view to reflect that. In the content type, I
did opt to keep the date field there. It can be used to sort the view
by default, but doesn't have to be displayed.
