Changed the logic of the "ensure vertical wall thickness" feature

slightly by inflating the projected top/bottom/bottom bridge surfaces
before they are added into a surface. This ensures, that the possible
projected infill areas merge with the perimeter supporting areas,
but the perimeter supporting areas will not be inflated on their own,
if there is no touching projection of a top/bottom/bottom bridge
surface.
