These are the changes from MOODLE_13_STABLE, merged into trunk
The tag MOODLE_13_MERGED on the MOODLE_13_STABLE branch now refers to this point
The biggest changes here are the fixes for HTML editor in all standard modules
Sections covers "weeks", "topics" and anything else that may come along.
Note, again, some databases have changed esp course_weeks -> course_sections
and several fields called "week" are now "section. Also course no longer
has an enddate, but instead has a numsections field.
