* API endpoint for certificate generation, an authenticated post with course
id requests that grading be carried out and a cert generated for
request.user in that course, using the usual grading and certificate
machinery (ie, it does not imply whitelisting, though whitelists and
blacklists will be respected)
- Logs each request as it comes in
- Calls xq.add_cert() and consequently, does grading synchronously on
this app host and then queues request for certificate agent.
- example usage:
```
curl --data "student_id=9999&course_id=Stanford/2013/Some_Class" http://127.0.0.1:8000/request_certificate
```
* Studio advanced setting added, "certificates_show_before_end", which
determines whether a course should permit certificates to be downloadable
by students before the coures's end date has passed.
- Modifications to dashboard view and templates to allow display of
certificate download links before course has ended.
(XXX: may declare failing students as failing before the course has ended.)
- To test, turn the setting on in a course which hasn't ended yet, and
force certificate generation for a student, then check their
dashboard.
Support incremental conversion of events from the old API to the new, in order to ensure the new system is working, enrollment events have been modified to make use of the new API.
RFC 2822 states that line lengths in emails must be less than 998.
Some MTA's add newlines to messages if any line exceeds a certain
limit (the exact limit varies). Sendmail goes so far as to add
'!\n' after the 990th character in a line. To ensure that bulk
mail messages look consistent long lines are wrapped to a
conservative length.

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
