[NTG-context] new structure code

Hi, i found a few bugs in the new structure code for mkiv. 1. the dot after numbered items is missing \starttext \startitemize[n] \item first item \item second item \stopitemize \stoptext 2. indices in headers work not in interactive mode \setupinteraction[state=start] \starttext \section{Section one\index{section}} \stoptext 3. \\ generates a backslash but was a space before \starttext text\\text \stoptext to be continued ...
