tdf#144788 SwNavigator: Group footnotes and endnotes separately
This is a follow-up patch to separately group footnotes and endnotes
under the Footnotes and Endnotes category. A separator line is shown to
distinguish between footnote and endnote entries. Entries above the
line are footnotes, entries below are endnotes. A tool tip is also
displayed to distinguish between them.
