Updates to depend on the latest version of XBlock, which includes
support for service-to-service (thirdparty) handler urls, which aren't
authenticated with a user (unlike handler requests coming from the
xblock client-side javascript).

Co-author: Ned Batchelder <ned@edx.org>

Fix LMS-1532 (partially instantiated XModules after an exception)

Fix for [LMS-1528], plus Changelog entry for the related feature

Also cleans up test_view_authentication to use user factories for
various user classes

Add release notes for 061a46be, concerning change to beta-tester groups

Sarina/dormsbee grades download

This guarantees that the ErrorModule will be created, instead of
potentially using a partially instatiated broken module. Fixes
[LMS-1532].

remove field_data_cache from grades.grade and grades.progress_summary

cleans grading code by adding wrappers

Ned/pr 1745 lms 1492

Webob represents uploaded files as cgi.FieldStorage objects.  The
XModule code expects pure Python file objects.  Each FieldStorage object
is wrapped to present the proper file interface, with file names.

LMS-1492

One test passes already, the other fails.  Fix in next commit.

These changes prepare for the changes to the tests that are coming, but
make no change to the behavior themselves.

Having ENABLE_S3_GRADE_DOWNLOADS enabled by default in common.py
could lead to surprising behavior for folks downstream. They'd
suddenly see a grade download screen on their new instructor
dashboard, but the links by default would be local files and
couldn't be used in an actual production environment. So we disable
by default and let people explicitly enable it and set it up for
S3 if they wish.

General code cleanup and addition of comments.

Instructor dashboard API unit tests.

LMS-58

Restrict grade report generation to 'is_superuser' users (can be overridden with
feature flag ALLOW_COURSE_STAFF_GRADE_DOWNLOADS); all staff users can download
generated files.

LMS-58

Hook up display of grade files ready for download to new instructor dashboard.

Ned/cherry pick pr 1740

Fix LMS-1493

This allows XModules (specifically CombinedOpenEnded) to use ajax_url
during their init functions (which would, before, have thrown an
exception).

[LMS-1493]

Under normal operation, XModules are reloaded on each request from a
student. CombinedOpenEnded modules have code that runs at initialization
that validates the students state. These changes makes that code run
during several long-form unit tests (testing CombinedOpenEnded across
multiple 'requests').

These tests are marked as expectedFailure because they now exhibit the
same failures as observed in [LMS-1493] (namely, the students state gets
reset, because CombinedOpenEnded interprets system.ajax_url raising an
error as meaning that the problem definition and the student answers are
in conflict)

'ignore' shouldn't be use for ascii conversion

The input string is not expected to contain any unicode characters

Adding a YAML file to demonstrate how to include anonymized user IDs in Studio elements.

The forcing of IDs to non-draft must happen in base.py instead of draft....

fixes issue where STATIC_URL was overwritten without git.revision

The draft.py solution only worked when the parent was also in the draft store.
