RandomSpawner Expansion

[Major Cooke]

Pull Request

If given the BOSS(DEATH) flags, RandomSpawners will remain as if the spawned had those flags. Useful for allowing collection of the spawned actor, since PostSpawn() requires knowing what actors want the information.

GetSpawn() retrieves the Chosen name and Spawned actor, since they're both protected in the event the Tracer pointer is changed.

Also, giving a randomspawner the BOSS flag will transfer that flag to any subsequent randomspawners spawned by it, but not BOSSDEATH.
