The function calendar_get_default_courses is responsible for loading all variants of calendar
course lists.

1 the list of courses that the current user will see events for in the site calendar.
2 the list of courses the current user will see when they are looking at a specific course calendar.
3 the list of course calendars the current user can create / edit events in.

When loading courses for the course filter on the calendar, we only need the id and shortname.

Consolidate the logic for the list of courses an admin will see in the calendar.

They will see all courses if calendar_admincanseeall is enabled.

They will see only courses they are enrolled in of calendar_admincanseeall is not enabled.

They will also see the current course, if they are admin and it is not already in the list.

This applies to the course selector and the create and update event forms.

The calendar link in the navigation block has also been changed to link to the current course calendar instead of the global
one.

This is something that changed in the upgraded Horde library. structure->findBody() returns string but structure->contentTypeMap is indexed with ints

This patch adds the label adminstration settings to the
label edit page.

Sneaking it in...

This method was used when the API was tied to students at risk model,
this method does not make sense any more as it is up to each target
to define what is a valid course.
