Subject: Add e_load_cal_source_async().

Similar to e_load_book_source_async() in libedataserverui (and may wind
up there eventually).  This replaces e_auth_new_cal_from_source().

  void   e_load_cal_source_async  (ESource *source,
                                   ECalSourceType source_type,
                                   icaltimezone *default_zone,
                                   GtkWindow *parent,
                                   GCancellable *cancellable,
                                   GAsyncReadyCallback callback,
                                   gpointer user_data);

  ECal * e_load_cal_source_finish (ESource *source,
                                   GAsyncResult *result,
                                   GError **error);
