Cdodge/restricted oauth2 applications

Allows ChoiceResponse problems to set correctness with python variables

determine choice correctness, as MultipleChoiceResponse problems already do.

Adds a unit test for this change, and for the existing MultipleChoiceResponse
computed correctness capability.

Update persistent grades asynchronously

ORA version update

Move dark_lang and lang_pref apps to openedx/core

Merge hotfix back to master.

Pull hotfix in to release branch.

Some Jenkins builds are erroring when attempting to set up the
npm environment with the error:

`npm ERR! cb() never called!`

Although it could point to a couple of different things, it is more classically
a sign of a dirty npm environment cache. Cleaning the cache at the start
of any given Jenkins job (which are sourced through this file) should
alleviate the problem.
