Reconnecting Token Generator for Annotation Tool
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
Fix paver python prereq paths
Fixed Unit Test Issues

Make course ids and usage ids opaque to LMS and Studio [partial commit]

This commit makes the embargo.tests module a real python module.

These keys are now objects with a limited interface, and the particular
internal representation is managed by the data storage layer (the
modulestore).

For the LMS, there should be no outward-facing changes to the system.
The keys are, for now, a change to internal representation only. For
Studio, the new serialized form of the keys is used in urls, to allow
for further migration in the future.

Adding additonal path to search for git information on sysadmin dashboard
When viewing the sysadmin dashboard courses tag, we also search the git

the course git repo to get hash, last commit, and last editor information
for each loaded course if available.
