==============================================================================
* Updates the Dokeos files from version 1.8.5 to version 1.8.6
* This script operates only in the case of an update, and only to change the
* active version number (and other things that might need a change) in the
* current configuration file.
* As of 1.8.6, the Dokeos version has been added to configuration.php to
* allow for edition (inc/conf is one of the directories that needs write
* permissions on upgrade).
* Being in configuration.php, it benefits from the configuration.dist.php
* advantages that a new version doesn't overwrite it, thus letting the old
* version be available until the end of the installation.
* @package dokeos.install
