Spawn and delete fireballs using new keybinds

+ Follow UE4 example for spawning and destroying actors
+ https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/SpawnAndDestroyActors/
+ This version uses hybrid C++ and Blueprints instead of doing one or the other
+ Functions to spawn and delete fireballs exposed by UFUNCTION() prefix
