- admin/update : filesystem synchronization process completely

rewritten. How to speed up sync ? by avoiding recursivity !

- admin/update : option to display verbose information details

- admin/update : option to simulate only. No database insert, delete or
  update will be made

- bug fixed : in admin/cat_list, if you delete a virtual category, you may
  create a gap in the rank list. This gap will generate errors when trying
  to move a category on this gap. Fixed by calling ordering and
  update_global_rank at category deletion.

- admin/cat_list, only one query to insert a new virtual category (no need
  of a second query to update uppercats and global_rank)

- for a given category, even if empty, the representing element must not be
  the one of a forbidden category for the current user

- generation time optionnaly displayed on the bottom of each page becomes
  more price : number of SQL queries and SQL time added.
