- improvement : screen admin/picture_modify rewritten. Presentation copied

from admin/cat_modify : fieldsets regroup fields. Ability to synchronize
  metadata for the displayed item.

- bug 110 fixed : "return to element view from element edition fails
  depending on permissions". If a reachable (for the connected admin)
  category is available, a "jump to" link is displayed, by default, using
  the category given in URL.

- bug fixed : in mass_updates function, the first item of $fields['update']
  has not always 0 for id (as in any array).

- modification : get_keywords function understands spaces as separator,
  allow less than 3 chars keywords, allow quotes.

- new : ability to allow HTML in picture or category description (false by
  default)
