/**
 * 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 is contained in the 
 *   wArg object:
 *  
 *   wArg.name              : Bookmark Name. The value to be prefilled
 *                            into the "Name: " field (if visible).
 *   wArg.description       : Bookmark description. The value to be added
 *                          : to the boomarks description field.
 *   wArg.url               : Bookmark URL: The location of the bookmark.
 *                            The value to be filled in the "Location: "
 *                            field (if visible).
 *   wArg.folderURI         : Bookmark Folder. The RDF Resource URI of the
 *                            folder that this bookmark should be created in.
 *   wArg.charset           : 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).
 *   wArg.bBookmarkAllTabs  : True if "Bookmark All Tabs" option is chosen,
 *                            false otherwise.
 *   wArg.objGroup[]        : If adding a group of tabs, this is an array
 *                            of wArg objects with name, URL and charset
 *                            properties, one for each group member.
 *   wArg.bWebPanel         : If the bookmark should become a web panel.
 *   wArg.keyword           : A suggested keyword for the bookmark. If this
 *                            argument is supplied, the keyword row is made
 *                            visible.
 *   wArg.bNeedKeyword      : Whether or not a keyword is required to add
 *                            the bookmark.
 *   wArg.postData          : PostData to be saved with this bookmark, 
 *                            in the format a string of name=value pairs
 *                            separated by CRLFs.
 *   wArg.feedURL           : feed URL for Livemarks (turns bookmark
 *                            into Livemark)
