From c08fa6f67ef5b149fdeb3bcc57045e629df8fff4 Mon Sep 17 00:00:00 2001
From: plegall <plg@piwigo.org>
Date: Sat, 4 Mar 2006 23:31:46 +0000
Subject: new feature: source/destination links between categories. Will we
 keep this feature? Code is complicated and very few people will understand
 how it works...

modification: #images.storage_category_id replaced by
#image_category.is_storage

improvement: many code refactoring to improve readibility

improvement: virtual category creation code was moved to a dedicated
function in order to be called from admin/cat_list.php and
admin/cat_modify.php (create a new destination category)
