Subject: [PATCH] Improve formatting of footnotes. (#107)

- improve footnote formatting using package `footmisc`
- make the references from the footnotes at the bottom of the page into links back to the occurence of the footnotes in the main text and introduce an option `disable-footnote-backlinks` to disable this new behaviour.
- load pkg footnotebackref after pkg footnotehyper
- make footnote prettifying optional using template var
