* Unit test for calendar_view_event_allowed() when dealing with course
events.

Instead of fetching the DB record AND then fetching it again (as
part of the vault->get_from_id() call, just use the legacy data
mapper and remove the DB call.

Some new styles added have caused the resulting zip
file to go beyond that accepted limit of 135000. So
increasing to 140000.

For usability, after selecting the subscription toggle action menu item,
a notification message will be shown to the user.

* Remove the subscribe link that's powered by YUI and
  subscribe_ajax.php. This will be replaced by the subscribe action
  menu item which utilises the subscription toggle template
  and calls the proper WS function for toggling discussion subscription.
* Nuke YUI module for toggling subscription and subscribe_ajax.php
  (about time!)

Implement sorting for the following columns:
* Discussion name
* Discussion starter name
* Group

* Move it under the discussion column.
* Change it to look like a label
* Plus limit the group name to 15 characters
* Plus some accessibility fixes:
  - Add labels to column headings.
  - Set discussion name as a row heading.

* Remove striped table row style
* Move subscribe icon to the action menu
* Update the action menu icon
* Remove the Last post column
* Removed the "Created" column and moved the date under "Started by"
* Added "Locked" and "Subscribed" indicators under discussion names.
* Added group name with the group picture. For groups without pictures,
  a default placeholder picture is now shown.

* This is how the usual moodle action menu is built.
* Removed the 'type="button"' attribute as it is not necessary.
* Added template context so it renders in the template library.

* Day, abbreviated month, and year (e.g. 28 Aug 2019)
* Day and abbreviated month (e.g. 28 Aug)

Disable the reset and fixed width content styling from the Boost
theme for the classic theme because it doesn't work well with
blocks.

When a user account is deleted don't render the user's name in
the forum. Instead we render "Deleted user".
