[DGD] Errors on console with continuations

[nikoroleva]

Just updated to latest cloud-server lib and getting errors on the
console when using distributed continuations and adding continuations
together. Here are some samples.

static void echo(object user, string str) {
    user->message(str + "\n");
}

/* ok */
void cmd_cont1(object user, string cmd, string str) {
    Continuation c;

    if (!str) {
        str = "the sound of silence";
    }

    c = new Continuation("echo", user, str);

    c->runNext();
}

/* Bad argument 1 (int) for function _F_continued */
void cmd_cont2(object user, string cmd, string str) {
    Continuation c;

    if (!str) {
        str = "the sound of silence";
    }

    c = new Continuation("echo", user, "echo 1 " + str);
    c += new Continuation("echo", user, "echo 2 " + str);

    c->runNext();
}

/* Too many arguments for function _F_timeoutContinuation */
void cmd_cont3(object user, string cmd, string str) {
    Continuation c;

    c = new DistContinuation(users(),
        1,
        "message",
        "Your significant mind notices the fabric of space.\n");

    c->runNext();
}
