more latexdiff hacks

- change link color from green to pinegreen. Looks better to me.
- split footnotes out from their text, so that latexdiff
  does not consider them as a unit
- mark field command as safe for latexdiff, otherwise it's not shown in red
- hack adding DIFaddtext within footnotes could not handle
  case where latexdiff inserted multiple DIFadd within the
  footnote. Instead, detect when footnote is within
  DIFaddbegin/DIFdelbegin, add an extra DIFaddbegin/DIFdelbegin
  within the footnote.
