Copy Variables between Blueprints

On old Unreal Engine yes, it worked fine.
But now I don’t even know if that thing is still working (I will probably have to rewrite some things) because from Unreal 4.19+ onwards a lot of those “Kismet Compiler” stuff changed.
Those changes caused a lot a headache with the ObjectPool plugin, etc.

For now I just noted here “find Property Transfer cpp source”, because I don’t know where it is lol

I will take a look tomorrow, this saturday.
