Built in an escape from sbObjectStep() if transform() is used. Has to be

done for lattices... these keep calling this during transform, causing
the lattice itself and its children (if soft) to remain static on same
position.

Real solution has to be 2-fold:
- store deformed lattice points in Lattice, as a "DispList"
- usage of proper depgraph :)

There's also the idea to keep simulating softbody during a transform, to
give feedback on what softbody does... later.
