Only allow the drag and drop functionality in the course index on pages
that provide alternatives to move course items such as the course
homepage and the course section view pages.
This is to meet the WCAG 2.2 Level AA Success Criterion 2.5.7 for
dragging movements.
See: https://www.w3.org/WAI/WCAG22/Understanding/dragging-movements
The string "sectionname" was an unnecessary coupling between
formats and other plugins. Now the generic name for a section
should be obtained using $format->get_generic_section_name.
This allow formats to use an alternative string for nameing
sections. This is especially important for rare formats like
the frontpage one that does not have a plugin lang file.
The page course/section.php has been created, to display the content of a
single section. This page will only accept sectionid (to get rid of the
legacy sectionnumber).
Some features of this page:
- The General section won't be displayed anymore above the selected
section.
- In the main course page content, regardless of the Course layout ("All
sections on one page" vs "One section per page"), all the section names
will link to the new page (except when editing mode is on).
