- Remove unused footnote section title option - Move away from maintaining a list of footnotes in the document (only needed for html export, potential maintainance overhead when modifying the document) and rather only build it on export when required. - HTML export: Rename all footnotes to numbers (so we can support anonymous footnote references by assigning them a number) and export footnotes in order of reference, not definition. The implementation of this makes it natural to also stop exporting unused footnote definitions so we do that as well.
