Update version of bok-choy.

Update schoolyourself-xblock to the latest version

Fix type field in thread list endpoint

Look for a consistent css class.

Update schoolyourself-xblock to the latest version, which contains 1 commit with a cosmetic change: https://github.com/schoolyourself/schoolyourself-xblock/commit/5e4d37716e3e72640e832e961f7cc0d38d4ec47b

Add fields to threads returned by Discussion API thread list endpoint

The former class, while less-flaky, does not always appear. (For example, if cohorts
are being toggled off.) This css class always appears. Initial findings point to
flakiness being a non-issue if we look for this class.

Addressing RTL inconsistencies on Verification process

Adds preferences API and updates users to V1 - fix

The API's type field should come from the CS data's thread_type field,
not its type field, which distinguishes comments from threads.

This commit adds fields that are related to the requesting user's
interaction with the thread (e.g. following).

make edxnotes bok-choy tests chrome-friendly

This eliminates some flakiness related to the loading of the notes page. It also
sets the 'no content' version of that page as a separate page object so testing
that case is more explicit.

[LTI Provider] Adding signals for scoring events

Update ease to 0.1.3

Add CCX/IDDE configuration to yaml_config.py

Currently, all XBlock/XModule handlers are lumped together in the
same transaction (courseware.module_render:handle_xblock_callback).
This makes it difficult to pinpoint problems with specific handlers.
With this change, the transaction name will now look like:

  OpenAssessmentBlockWithMixins.save_submission
  CapaDescriptorWithMixins.xmodule_handler/problem_show
