Set whether the user confirmed the dialog.
This method is used for webkit_script_dialog_confirm and webkit_script_dialog_before_unload_confirm dialogs when script_dialog signal is emitted to set whether the user confirmed the dialog or not. The default implementation of script_dialog signal sets true when the OK or Stay buttons are clicked and false otherwise. It's an error to use this method with a ScriptDialog that is not of type webkit_script_dialog_confirm or webkit_script_dialog_before_unload_confirm
