/**
* Main script for the links tool.
*
* Features:
* - Organize links into categories;
* - favorites/bookmarks-like interface;
* - move links up/down within a category;
* - move categories up/down;
* - expand/collapse all categories (except the main "non"-category);
* - add link to 'root' category => category-less link is always visible.
*
* @author Julio Montoya code rewritten
* @author Patrick Cool
* @author René Haentjens, added CSV file import (October 2004)
