Move common code to detect whether a part has a valid sit target into a SOP property rather than being repeated in SP. 

This also makes the detection in SP.FindNextAvailableSitTarget() and SendSitResponse() identical.
Previously they varied slightly (SendSitResponse didn't check for an older type of invalid quaternion) but the practical effect is most probably zero.
