Changes based on https://set.kuleuven.be/intranet-associatie/ADS/template_docs/titlepage.doc
Added the copyright year.  It would probably be better to reuse the date variable for that.
Added the "Uitgegeven in eigen beheer" and the author name.
Changed the order of ISBN and D number (cfr. the ADS template)
Changed the font to sans-serif and made it script size (more similar to how it is in the ADS template).
