Remove/fix the BlueprintProfiler

It causes memory leaks and it can’t be deactivated after being activated once. And most of the time it doesn’t show anything on the nodes.

It is the button called “Profiler” at the top when editing a blueprint.

Just as I told here : https://forums.unrealengine.com/showthread.php?132826-BlueprintProfiler-can-t-be-deactivated-HUGE-MEMORY-LEAK

Wow, it can’t be deactivated? I’m glad I haven’t noticed it, then.

Yes, even when it’s deactivated, it still says “instrumentation is active”, and it hogs memory

I have a proof of what I’m saying : Once I rebuilt the BP (so the instrumentation is off and stays off), the memory leak was gone completely, and I didn’t change anything.
