As an editor, I would like to have Columns without the need to fill in the header.

Tasks

• Make column header filed not compulsory on all Columns styles.
• On the frontend check if either of the important fields is there in order to display the column.

Fields check

• For all Columns styles: Header or Body should be present to render the column.

Notes
This won't break existing content, since all existing content has at least a Header.
