Number chapters and sections in Instructor view

[sahi1l]

Describe the bug
I assign reading by chapter number and section number; it would be convenient if chapters were referred to by number AND title everywhere.

To Reproduce
Steps to reproduce the behavior:

1. Visit https://runestone.academy/runestone/dashboard/index?chapter=Iteration

2. Click on "Select Chapter", and note the lack of numbers.

3. Look under "Overall Progression" and note the section names are not numbered.

4. Visit https://runestone.academy/runestone/admin/grading.

5. Choose "Chapter" from the first menu.

6. See that the names of the chapters appear (in random order!) but the numbers do not.

7. Visit https://runestone.academy/runestone/admin/assignments

8. Click on "Readings" to open it up.

9. Note the lack of chapter numbers and section numbers that are listed below.
