/**
 * Add Bookmark Dialog. 
 * ====================
 * 
 * This is a generic bookmark dialog that allows for bookmark addition
 * and folder selection. It can be opened with various parameters that 
 * result in appearance/purpose differences and initial state. 
 * 
 * Use: Open with 'openDialog', with the flags 
 *        'centerscreen,chrome,dialog=no,resizable=yes'
 * 
 * Parameters: 
 *   Apart from the standard openDialog parameters, this dialog can 
 *   be passed additional information, which gets mapped to the 
 *   window.arguments array:
 * 
 *   window.arguments[0]: Bookmark Name. The value to be prefilled
 *                        into the "Name: " field (if visible).
 *   window.arguments[1]: Bookmark URL: The location of the bookmark.
 *                        The value to be filled in the "Location: "
 *                        field (if visible).
 *   window.arguments[2]: Bookmark Folder. The RDF Resource URI of the
 *                        folder that this bookmark should be created in.
 *   window.arguments[3]: Bookmark Charset. The charset that should be
 *                        used when adding a bookmark to the specified
 *                        URL. (Usually the charset of the current 
 *                        document when launching this window). 
 *   window.arguments[4]: The mode of operation. See notes for details.
 *   window.arguments[5]: If the mode is "addGroup", this is an array
 *                        of objects with name, URL and charset
 *                        properties, one for each group member.
