* 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
*
* DOKEOS_INSTALL 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 DOKEOS_INSTALL 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
