- access to a nurbs points was broken - sizeof(BPoint) vs sizeof(BPoint *)
- renamed CurvePoint --> SplinePoint
- renamed point.point --> point.co (less stupid, matches vertex.co)
- access point.co was a 3D vector rather then a 4D vector with the Nurbs weight included.
- rename point.weight --> point.weight_softbody, move point.point[3] --> point.weight
- sorted RNA structs (for pedaticness only)
