C++14 and OS X 10.11

[timdecode]

It looks like some of the latest commits have started to use some C++14 features, such as variable templates. Out of the box, C++14 is not supported by Unreal (at least on OS X) without rebuilding the build tools.

The error I got was:

error: variable templates are a C++14 extension [-Werror,-Wc++14-extensions] FRuntimeMeshVertex<WantsPosition, WantsNormal, WantsTangent, WantsColor, NumWantedUVChannels, NormalTangentType, UVType>::TypeInfo;

(I do not include the line number as I was reordering the declarations in RuntimeMeshGenericVertex.h to get it to compile on OS X)

Well, I know I've only attempted to build the past few commits on my primary machine, but there shouldn't be anything in there that requires c++14, and I know I'm building with the stock build config of the engine, but it is MSVC. Unfortunately I don't really have access to an OS X machine right now so I'm limited on my testing abilities there. The file that's from I don't think I've touched recently in master other than moving it into a submodule.

Thanks! I'll give it another try when I'm on an OS X machine tomorrow.

Never mind, this appears to be an artifact of the changes I made to fix the build errors in RuntimeMeshGenericVertex.h
