EPUB export, fixed layout: add chapter names to the navigation document

Extend vcl::PDFExtOutDevData so that it's possible to use it outside the
PDF export; this way the EPUB export can know which chapters start on
which page.

This means fixed and reflowable layout has the same table of contents,
instead of just Page <N> in the fixed layout case.

Or did the steps behind him mean that one of many law officers in town was on to him and just waiting to pounce and snap those cuffs on his wrists? He nervously looked all around.
