BehaviorTreeEnded never called

[cd1232]

This may already be a dead project, but I've been implementing this and have almost everything working but an order never knows when it's finished.

There's a missing call to BehaviorTreeEnded in the RTSAIController, and it's blueprint callable. Not sure where/when to call it. It could be called when a behavior tree has ended but it It needs a EBTNodeResult::Type Result passed in.

There is a virtual function OnTreeFinished in the behavior tree component that could be used but I am not sure how to say whether it succeeded or not
