- elements batch management : element_set page becomes the frontend to

element_set_global and element_set_unit, infos_images (after a long time
  of use) become deprecated : the more powerful element_set is used
  instead. Consequently, batch management concerns caddie but also "normal
  categories".

- refactoring code in admin.php to include the sub-file (clearer)

- caddie : function fill_caddie replaces the code in category.php and can be
  used in admin/element_set.php

- caddie : caddie table is added in delete_elements function
