some changes that were supposed to be in sakai.properties for the new course management stuff have not made it in:
Without these the find course page will not function within the demo
version of Sakai.
When Sakai is run with the sakai.demo flag the CM implementation data
loader adds a bunch of course, department and section definitions to the
database. sakai.properties needs to identify two critical pieces of
metadata for this data to be usable by the "find a course" feature in
site setup. It needs to know the "category" of course thing it should
pull from the database in order to represent the "department" level
within the organization, and it needs to know what to call the
"department" level within the UI.
