Display unique section numbers for Canvas courses
Fixed CanvasCourse parcelling/unparcelling
Properly show course unique id on course map

Instead of appending the id to the course code (which actually shows it
in the top bar on the detail page which it shouldn't), it gets appended
in the course list adapter. This makes the display more consistent with
the way blackboard classes are shown.
