This commit adds a new setting to always display course sections
as links (if possible).
MDL-36236 cache: clarified locking strings

We copy the cachedef_locking string as that cache definition is

AMOS BEGIN

MDL-48425 course: management behat tests improved
MDL-48290 behat: Add log out after checking exported file

If the download step is the last in the scenario then we
can sometimes run into the situation where the download page

reset (generating an error). By putting a logout step we avoid
behat doing the reset until we are off that page.
