Courses with course visibility set to hide should be labelled 'Hidden from students' in the course overview

If a course is set as hidden in the course settings (course visibility), this course does not appear any differently from open courses in the Course Overview block. The hidden course name should ideally be differentiated from courses that are set as open ("show"). It has always been this way in previous versions. Also, the Courses (My Courses) block continues to show these hidden courses using dimmed/greyed out text.

As a side note, the concept of "hidden course" now has two meanings – it's somewhat confusing now – and this has implications in the Course Overview block. A course can be "hidden" (course visibility) in the course settings (so students can't access it), and a course can be "hidden" in the Course Overview block by an individual user so it doesn't display in the Course Overview block for that user (unless the hidden course view is selected).
