Links and normal text should have at least a colour contrast ratio
of 3:1. To achieve this, $body-color will be using the darker
shade of gray $gray-900 (#212529).
* Darkened the link and clickable icon colours inside coloured events.
* Added borders around event colour indicators inside the month-view of
the calendar for better contrast against the white background.

Why 20210525? (25th May 2021) ?
Because master is going to be Moodle 4.0, to be released
on November 2021. And, until then, we are going to have
a couple of "intermediate" releases:
- Moodle 3.10 to be released 9th November 2020. (2020110900)
This version will be using versions from today to 2020110900
(once it's released the YYYYMMDD part stops advancing).
- Moodle 3.11 to be released 10th May 2021. (2021051000)
This version will be using versions from 3.10 release to 2021051000
(once it's released the YYYYMMDD part stops advancing).
That means that all versions from today to 2021051000 are going
to be used by those 2 "intermediate" releases (3.10 and 3.11).
And we cannot use them in master, because it's forbidden to have
any overlapping of versions between branches (or different upgrade
paths will fail).
So, get that 2021051000, let's add it a couple of weeks to cover
the on-sync period (or a 2 weeks delay max!) and, the first version
that master can "own" in exclusive (without any overlap) is, exactly,
25th May 2021, hence our 20210525.
* Added aria-label for category single select element when on Courses
view mode.
* Fix correct labelling of custom control checkboxes. Instead of adding
aria-label in the label element, add an sr-only span within the label.
* Remove inappropriate 'group' role for the list of courses.
The list of courses is not being rendered as a tree structure
so adding a 'group' role to the list of courses is not really
necessary.
* Add aria-label for the search courses field.
* Add legend for the search courses fieldset.
* Use the primary colour for the category selection highlight instead
of the info colour.
* Changed the labels for the up/down icons using moveup/movedown
lang strings.
Where an element, like an `alert`, is closed it is removed from the DOM
before the event fires (this is a correct behaviour).
This means that the final event confirming that the action happened
(i.e. close => closed) fires, but does not bubble up the DOM to the
document.body.
This change moves the end event listener to only be added after a start
event has been fired, and to attach directly to the HTMLElement where it
will be fired. This means that the Event handler will still be called,
even though it has been removed from the DOM, because it does not need
to bubble up to the body.
