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);
