Updates for language auto detect, fixes for PHP 7.4

There was a bug in ther SQL interface class where the folder was just called "Interface" which is not an allowed Namespace name. Renamed to SqlInterface Moved the detect lang/etc function used in Form/Generate, Template/SmartyExtend and Admin/Backend to Language/GetSettings. Fixed some test class calls
