Allow posters to edit/delete their own discussion postings. Controlled by
course parameter set via PARM. Previous versions of postings are preserved.
Deleted postings are hidden. Course Coordinators etc. will be able to see
all versions of postings (interface still needed). Editing currently works for
resource discussions, but not bulletin boards (work in progress).
