In order to achieve good colour contrast between dimmed text and striped
table rows, the background colour of the striped rows are being
lightened to 0.03 alpha. While $gray-600 is being adjusted to a bit
darker shade of #6a737b. This gives a colour contrast ratio of 4.5:1
between the dimmed text colour and the striped table row background
which meets WCAG 2.1 Level AA requirements.
Comparing the normal font colour (#212529) with the adjusted dimmed text
colour gives a contrast ratio of 3.20:1 which meets WCAG 2.1 Level AA
requirements and still makes them distinguishable from one another.
- Modified SQL in get_data() to get the activity completion of all course modules without calling get_fast_modinfo() to reduce the DB queries.
- Building activity completion cache for the whole course in one time instead of building the cache for each course module by passing $wholecourse = true to get_data()
This implementation will introduce a qbank plugin "previewquestion"
which will view the preview question action in the question bank
actions by replacing the core classes, scripts and yui modules.
This plugin will also replace the preview option in the edit
question form. Having this plugin will give users the
flexibility of enabling or disabling this feature from
the question bank view.
This change will also allow other qbank plugins to add
elements or information in the preview question page
by implementing a callback. It also changes the pop
up to page redirect from base view page to make sure
any changes in preview reflects in the base view, for
example, comments added and the number of comments in
the comments colum changes while back from the preview
page. Other locations like edit and qtype plugins where
the preview is implemented, stays the same.

Fetching the counts of unread posts should only include unread regular
posts or unread private reply posts directed to the user unless the user
has the capability to read private replies.
In order to retrieve the correct counts, we also need to loop through
each forum instance in the course to check the capability of the user to
read private replies in each forum.
We should ensure that users being exported are enrolled on the
course being exported from. In courses where the current user can't
access all groups we should ensure that users being exported belong
to the same groups as them.
LaTeX documents have a preamble section and admins can use a \newcommand
statement to define new commands there (or to give an alias to another
command). This commit makes sure no blocked command can escape
sanitization by being used in a new seemingly harmless command that is
defined in the LaTeX preamble.
