Fleshing out method for Renamed events. It has to account for instances where the file being renamed exists in the destination directory and instances where it doesn't.
OnRenamed method can now handle calls for instances when the target autobackup directory contains the file being renamed, in which case it avoids file actions in the game save directory, as well as cases where the target autobackup directory does not contain the file being renamed, in which case it utilizes OnChanged's in/out stream copy method.
