Changed the K2Node_Message to expand and attempt to cast the incoming reference as a ULevelStreaming reference, get the level script actor, and cast that to the interface. Exposed for Blueprints (BP internal use only) ULevelStreaming::GetLevelScriptActor All levels can now have a BP interface added to them. #jira UE-16706 - Implement Level Blueprint Interface Communication [CL 2597586 by Michael Schoell in Main branch]
