Additional logic to handle more course_image URL edge cases
This changes logic to allow more missed use cases of course_image to
work properly.  The cases are:

. XML courses with the course_image attribute set
. Mongo courses that are imported without a contentstore
. Mongo courses that have course_image set but don't have a content store

It also exports default images_static_course.jpg to
images/static_course.jpg to handle a use case where a course author
uploaded an image to the default location in studio without using the
studio interface for adding course images, they then export the course, and then
import it without a contentstore
Removed diacritic mention and explained token

Certs: pass course name on queue

Stanford had a problem a few times that certificate requests had
different values for the course display name and the course name printed
on the certificate and verification pages because of human error. This
passes the course display name on the queue to the certificate requests,
so that at least one place where the course name is reproduced (the
certificate agent's settings.py) can be eliminated.

Remove google analytics tracking from iframes used in Drupal course about pages

This fixes two issues:
 - if the course pointed to doesn't exist, GA was added to the iframe twice
 - more importantly, we don't want to count these as separate views anyway--
   we just care about the about page itself.
 - I also added a note about where we would put our segment.io widget if we want it
   later
