  - tdf#153549 update because Chapter Numbering -> Heading Numbering
    
       First of multipart patch to update help pages because of
       name change to the dialog that assigns numbering schemes
       to headings. Patch focuses on pages that describe the
       Tools - Heading Numbering dialog. Where possible, German
       Ids were renamed.
    
       For "Numbering" page, controls were reordered to correspond
       to the current order in the dialog.
