Fix child parts having their rotations broken -- we have to iterate f…

…orwards over the parts list, not backwards, because if we iterate backwards then we'll be setting parent positions and rotations after child positions and rotations, which will cause child pos/rot to be recalculated. KSP keeps parts in hierarchy-order so iterating forwards is safe.
