rfctr: _Header and _Footer take header/footer type
In preparation for adding even-page and first-page header and footer properties, pass the WD_HEADER_FOOTER_INDEX member identifying the header or footer type (primary, first, even) to _Header and _Footer on construction. This will allow each of these classes to serve for all three header/footer types.
