* separate stepconf description text (stepnames) from stepconf for better localization handling in DB
   ATTENTION !!!!!!
   This is a breaking change in the data model. Existing stepnames will be deleted and have to be added again after upgrade.
* removed static function <tt> Tx_ThRating_Utility_ExtensionManagementUtility::updateStepconf</tt>
* added static function <tt> Tx_ThRating_Utility_ExtensionManagementUtility::setStepname</tt>
