Support for Local Gameplay Cues

[Mighteemouse3]

Support for Local Gameplay Cues as discussed in GASDocumentation here would be great for compensating for network latency and generally keeping down on RPCs. Optimal if they're exposed to BP for easy use in Gameplay Ability Blueprints. Firing them locally would be preferable to spawning particle effects and sounds by reference, which is currently what you need to do if you with to avoid network latency.
