AK1000: Need to add `IIndirectActorProducer` support for creating actor instances

[Aaron Stannard]

Need this to support things like DI et al:

private class TestProducer : IIndirectActorProducer
        {
            TestLatch latchActor;

            public TestProducer(TestLatch lp, TestLatch la)
            {
                latchActor = la;
                lp.Reset();
                lp.CountDown();
            }

            public ActorBase Produce()
            {
                latchActor.CountDown();
                return new PropsTestActor();
            }

            public Type ActorType
            {
                get { return typeof(PropsTestActor); }
            }


            public void Release(ActorBase actor)
            {
                actor = null;
            }
        }

This should not trigger AK1000.
