This is a patch to the c172p fdm to add pointmasses for all four
occupant positions and baggage. The X locations were taken from the
c172 type certificate 3A12 dated September 15, 1998. As the new
pointmasses have a weight of 0 they will not affect the current model,
however we are extending the FlightGear weight and balance dialog for
JSBSim and the pointmasses have to be defined.
