/**
 * The panel is initialized based on data given in the js object passed
 * as window.arguments[0]. The object must have the following fields set:
 *   @ action (String). Possible values:
 *     - "add" - for adding a new item.
 *       @ type (String). Possible values:
 *         - "bookmark"
 *           @ loadBookmarkInSidebar - optional, the default state for the
 *             "Load this bookmark in the sidebar" field.
 *         - "folder"
 *           @ URIList (Array of nsIURI objects) - optional, list of uris to
 *             be bookmarked under the new folder.
 *         - "livemark"
 *       @ uri (nsIURI object) - optional, the default uri for the new item.
 *         The property is not used for the "folder with items" type.
 *       @ title (String) - optional, the default title for the new item.
 *       @ description (String) - optional, the default description for the new
 *         item.
 *       @ defaultInsertionPoint (InsertionPoint JS object) - optional, the
 *         default insertion point for the new item.
 *       @ keyword (String) - optional, the default keyword for the new item.
 *       @ postData (String) - optional, POST data to accompany the keyword.
 *       @ charSet (String) - optional, character-set to accompany the keyword.
 *      Notes:
 *        1) If |uri| is set for a bookmark/livemark item and |title| isn't,
 *           the dialog will query the history tables for the title associated
 *           with the given uri. If the dialog is set to adding a folder with
 *           bookmark items under it (see URIList), a default static title is
 *           used ("[Folder Name]").
 *        2) The index field of the default insertion point is ignored if
 *           the folder picker is shown.
 *     - "edit" - for editing a bookmark item or a folder.
 *       @ type (String). Possible values:
 *         - "bookmark"
 *           @ itemId (Integer) - the id of the bookmark item.
 *         - "folder" (also applies to livemarks)
 *           @ itemId (Integer) - the id of the folder.
 *   @ hiddenRows (Strings array) - optional, list of rows to be hidden
 *     regardless of the item edited or added by the dialog.
 *     Possible values:
 *     - "title"
 *     - "location"
 *     - "description"
 *     - "keyword"
 *     - "tags"
 *     - "loadInSidebar"
 *     - "feedLocation"
 *     - "siteLocation"
 *     - "folderPicker" - hides both the tree and the menu.
 *   @ readOnly (Boolean) - optional, states if the panel should be read-only
 *
 * window.arguments[0].performed is set to true if any transaction has
 * been performed by the dialog.
