* Lighten info container.
* Fix colour contrast for the question container by
- Lightening the background a bit
- Darkening the text colour a bit
- Making sure the link colour has good colour contrast against the
question text.
* Fix colour contrast for the comments container by
- Lightening the text colour a bit
- Darkening the link colour a bit for better colour contrast against
the feedback text.
The current red, blue, and green colours achieve the minimum colour
contrast against a white background. However, when they're against
coloured background, text with these colours will easily fail the
4.5:1 contrast ratio requirement for Level AA.
The updated colours now have the following contrast ratio against a
white background:
* Blue - #0f6fc5 (5.12:1, from 4.58:1)
* Green - #357a32 (5.27:1, from 4.63:1)
* Red - #ca3120 (5.29:1, from 4.59:1)

As temporary editor files have been moved from core_h5p/editor to
user/draft, they can be removed (to clean unused DB entries).
This is a backport of MDL-68909
Makes sure the guest user context exists when fetching
the recommended modules. If the context does not exist
an exception is being thrown describing the problem.
The remove_course_contents function did not delete data from
course_module_completion table in most cases, resulting in large
quantities of orphaned data.
The new API works on normal databases (by deleting data based on the
subquery) and also on MySQL (by deleting the data using a weird join
on the subquery).
Before there is a conversation, messages between users are sent
using core_message_send_instant_messages instead of
core_message_send_messages_to_conversation.
That method had an undefined $errormessage variable, ultimately
causing the problem detected on message_post_message()/message_send()
to never been returned by the external.
This just adds the same error than already existing conversations do,
but returning it as warning, for BC, JS will show it.
Without this, there's a code path that under the right circumstances is hit and
results in a query with `FROM (mdl_event) ev` in it - which is not valid syntax
under postgres.
