Updated for new versions of Jelix + small bugfix

Replaced obsolete $gJConfig variable with its static class function equivalent for new versions of Jelix : jApp::config().

"alt" and "title" attributes where incorrectly set for the $info->htmlLabel (they were set to "SQL queries", probably because of a copy/paste from the Jelix lib). It has been corrected to "Technical infos" for both.
