Changes to the certificates page requested

[QualisLindaSheets]

There are so many records on the certificates page now that it is difficult to know which course certificates you are viewing. We would like a couple of enhancements to this page.

1. Add the course name to each record so whether viewing on the page or downloading to Excel, you can at a glance know which course the certificate is for.
2. Add a course filter option at the top of the screen. With the number of users and courses increasing, it will be helpful to be able to filter for the course needed. We should be able to view all certificates (grouped by course, as it is now) or only for the filtered course.

If the addition of the course name to the record is not a difficult change, please make this change also to the other two admin pages (join requests and demographics).

We'll work on getting a $ estimate for this feature. Putting in backlog for now.
