Added recursive directory search in lib directory

Example: (last is set inside lib/orm folder)
/home/www/modules/OrmSkeleton/lib/class.entity.citySkeleton.php
(class.entity.citySkeleton.php)
/home/www/modules/OrmSkeleton/lib/class.entity.userSkeleton.php
(class.entity.userSkeleton.php)
/home/www/modules/OrmSkeleton/lib/class.entity.countrySkeleton.php
(class.entity.countrySkeleton.php)
/home/www/modules/SchoolLib/lib/orm/class.entity.statusSchoolLib.php
(class.entity.statusSchoolLib.php)
