[NTG-context] Two stopper bugs (tables of contents and head titles)

Hi, I've noticed two bugs (I think) with stoppers: 1) Stoppers in table of contents When you set stopper=~ in \setuplist the stopper also appears for unnumbered heads of the table of contents (chapters, sections etc. that are in frontmatter and backmatter). 2) Stoppers in head titles When you set stopper=~ in \setuphead it has no effect. Apparently all spaces (\,| |~|\ |\quad|\qquad) are ignored here, because when you set stopper=abc it works. Will Hans fix these two bugs in next betas?
