Merge ImplementsInterface and Cast

[anonymous_user_566478b0]

Hello,

I would like to ask/request if there are any plans on merging
Actor->GetClass()->ImplementsInterface(IInterface::StaticClass())
and
Cast<IInterface>(Actor)

It is little confusing because first one works when blueprint class implements interface and second one does not (I think it should).

And TSubobjectOf<T> for interface type constraints too! Pretty please
