#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!

#UpgradeNotes:
If one of your classes implements IMessageHandler, you must remove GetHandledMessageType() and instead verify the type of message in HandleMessage(). See TMessageHandler<> for details.

Details view supports displaying UProperties from external UStruct's that are not a property of a UObject.

* Variadic version is compiler-switched on variadic template support.
* Variadic version doesn't repeatedly include lots of the same headers to generate code.
* Tidying up of some original delegate stuff.
* Removed return type from lambda in K2Node_TemporaryVariable which was causing a Clang ICE.
* TTuple, TIntegerSequence and associated functionality - generic, but currently only implementation details of delegates and not yet for use in general code because there is no non-variadic version of them.
* MessageRouter and MessageTracer updated to use an actual delegate instead of implementation-specific identifiers.
* TTypeWrapper and TUnwrapType added to aid 'recursive' template definitions.
* C4373 disabled on VC - was only hitting this warning during development, but it's good to disable it anyway, as it's a 'this code is now standard' warning.
