Christoph Oelckers 17a2666bd4 - moved DisplayName, the last remaining PlayerPawn meta property, to PClassActor so that PClassPlayerPawn could be removed.
Now all actors have the same metaclass and therefore it will always be the same size which will finally allow some needed changes to the type system which couldn't be done because it was occasionally necessary to replace tentatively created classes due to size mismatches.
