- Ensure that only a course import is saved to the draft branch and then
published. A content library has only a single 'library' branch.
- Add a fields parameter to the create_library call so the call has the
correct number of parameters.
- Add tests which import content libraries using different test methods
and with different branch settings.
- Add test which imports a content library and then exports it.
- Use XBlock module version that supports XML-serialized String of None.
- Add re-import of content library and equality comparison to test.
- Allow get_items to be called on LibraryLocators.

Update translations (autogenerated message)

Despite db_index=True, Django didn't generate an index

Adding the -n option to the Sphinx build invocation

This should not be needed, we specify ATOMIC_REQUESTS on each DB

student_module_id is the primary way into this table, not having an
index is disastrous with real data.

Adding the -n option to the Sphinx build invocation so that WARNINGs will be treated as ERRORs. This will cause builds to fail if Sphinx cannot import modules for its autoclass directives. Currently, they fail silently and leave gaps in the published HTML where docstring content should have been.
