Add Destroy Controller node

[Starkium]

Epic games by default overides the destroy node in blueprints relating to controllers so that beginers don't accidentally destroy their controller. I created a node to intentionally destroy controllers instead of changing possesion logic. I have a zombie game with many ai in an open world so this process got tedious. I figured others could bennefit from this simple overide as well.

Thanks for this, it would be great if you could exclude the .vs additions of several MB and have only source code additions :)
