[NTG-context] Allow pagebreaks in footnotes

Hi Is there a setting that prevents footnotes from spreading over more than one page? I have a document where this seems to be the case, but I don't know why. It just looks like ConTeXt tries to keep the complete footnote on one page, which leads to ugly white space at the end of almost every page. (LaTeX has \interfootnotelinepenalty to customize this, but what about ConTeXt?) Best Denis
