#UpgradeNotes:
The TStructOpsTypeTraits<>::WithMessaging type trait is no longer necessary for UStructs intended to be used as messages, because UObject creation and destruction is now thread-safe, and message types no longer need to be pre-cached. You can now use any existing and custom UStruct class in the Engine as messages. I ran the Editor for a couple hours with the profiler enabled and did not have any stability issues. If you experience any Messaging related crashes, please let me know asap, thanks!

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.
