Log message:
	The method intersection_preserving_enlarge_assign() now returns a boolean:
	if false is returned the intersection is empty.
	Using the new return value, improved the implementation for Pointset_Powerset
	by dropping those disjuncts that have empty intersection with all of the
	disjunct of the context.
	Corrected a bug in the Polyhedron method regarding the correct handling
	of equality constraints.
