used to differentiate different kinds of enrollments (currently, all enrollments
are honor certificate enrollments). The `is_active` flag will be used to
deactivate enrollments without deleting them, so that we know what course you
*were* enrolled in. Because of the latter change, enrollment and unenrollment
logic has been consolidated into the model -- you should use new class methods
to `enroll()`, `unenroll()`, and to check `is_enrolled()`, instead of creating
CourseEnrollment objects or querying them directly.

a delay of mouse inactivity). The video player size does not change - the video
is down-sized and placed in the middle of the black area.
3.) All source code of Video Alpha 2 is written in JavaScript. It is not a basic
conversion from CoffeeScript. The structure of the player has been changed.
4.) A lot of additional unit tests.
LMS: Added user preferences (arbitrary user/key/value tuples, for which
which user/key is unique) and a REST API for reading users and

X-Edx-Api-Key HTTP header (which must match settings.EDX_API_KEY; if
the setting is not present, the API is disabled).
LMS: Added endpoints for AJAX requests to enable/disable notifications
(which are not yet implemented) and a one-click unsubscribe page.

history of background tasks for a given problem and student.
Blades: Small UX fix on capa multiple-choice problems. Make labels only
as wide as the text to reduce accidental choice selections.

than cloning a db record.

tasks that are currently running for the course, and an option to
see a history of background tasks for a given problem.

LMS: Forums. Added handling for case where discussion module can get `None` as
value of lms.start in `lms/djangoapps/django_comment_client/utils.py`
