Changeset [40606c2fbe4982c4c47adc44db7e4ba0852f9f7a] by dleffler

Changed migration of headlines to text items in preparation for headline controller deprecation.

Still gives the anomaly of double headlines after migration because the old headline module didn't display the module title. The post-migrate FIX is to decide if you want an h1 title, make the text item title blank, or if you want an h2 title, make the module title blank.
