Smarty Extended class update

Move all smarty and path settings into the Smarty Extended class

the include files <admin|frontend>_set_paths.php and <admin|frontend>_smarty.php

are deprecated.

For special frontend smarty (which will be not used in future anyway) a
dedicated sub class to Smarty Extended with its own methods should be
created
