ActorClass dropdown should search within actor class names
Currently the suggestions in the actor class dropdown menu (when adding or editing an actor ref) only contain actors where the actor name begins with the user input. It would be usefull to be able to also search for actorname which contain the user input anywhere within the name.
E.g.: If I type "Blinky" into the input field I would like to see the "AHeartbeatBlinky" actor as a suggestion.
