- global categories' options : instead of N horizontal tabs on a single

page, N options in the left menu (but the same backend)

- categories.global_rank : new calculated field. It gives a global rank of
  the category among all others (updated during ordering)

- category.php page : menu is generated faster thanks to
  categories.global_rank, recursivity becomes useless :-)

- new function to display select box with a set of categories :
  display_select_cat_wrapper

- cat_options : instead of using 1 multiselect for true/false items, using 1
  multiselect for true, and another one for false. The form provides buttons
  with arrows to switch categories from one multiselect to another

- deletion of obsolete function display_categories (working with the old
  template system)

- deletion of obsolete functions get_user_plain_structure,
  create_user_structure, get_user_subcat_ids, update_structure, count_images
  : useless thanks to global_rank
