Luoshuang's GPULightmass

[motorsep]

If having to switch between the original and modded version of the editor is too much of a hassle, some might find it easier to build from source using my fork.

I have tested and can confirm that packaging using a locally built, from source, version of UE4 works just fine.

So, do I just cherry pick GPULightmass from your fork and add it to my source fork ?
