* Updates the Dokeos files from version 1.6.x to version 1.8.0
* IMPORTANT: This script has to be included by install/index.php or
* update_courses.php
*
* SYSTEM_INSTALLATION is defined in the install/index.php (means that we are in
* the regular upgrade process)
*
* DOKEOS_COURSE_UPDATE is defined in update_courses.php (means we are
* executing update_courses.php to update courses separately)
*
* When SYSTEM_INSTALLATION or DOKEOS_COURSE_UPDATE are defined, do for every course:
* - create a new set of directories that reflect the new tools offered by 1.8
* - record an item_property for each directory added
*
* @package dokeos.install
