Export to IMS now exports discussion content - uses lonfeedback::listdiscussion(). Modification to export of templated documents (syllabus, aboutme, simplepage etc.) to IMS. Simple problems now converted to standard LON-CAPA problem format before export to IMS. Same routines could be used to dump simple problems to CSTR.
