Current hyperref not compatible with jydiss

Take the example.tex, insert usepackage declaration for hyperref before document begins, run LaTeX, and you'll get

! Use of \NR@schapter doesn't match its definition.
\H@old@schapter ...\NR@gettitle {#1}\NR@schapter {
                                                  #1}
l.87 \begin{document}

Apparently, the hacks done to schapter are not anymore compatible with hyperref.

It might take a while to fix this, sorry…
