The Ground Motion tool now takes into account certain unselected elements

Unselected objects from the foundation group are now also parented to the ground for user convenience. One can add neighboring buildings to this group so that they share the ground motion more easily, so selecting these structures and suppressing discretization etc. is not necessary.
