Benoit Bolsee 5b722b1e87 BGE: replace mesh works for Soft Body (including reinstantiation of physics soft body mesh).
Even a static mesh can be used as replacement: the mesh
will be instantiated with the soft body settings of the
object. The position and orientation of the soft body
is preserved after the replacement.

Known limitation: the velocity of the soft body is reset
aftet the replacement. This is because soft body don't
have a well defined velocity.
