Added files:
	tests          : polydifference2.cc 

Log message:
	Added a new test showing two bugs:
	- the assignment operator on Polyhedron breaks the invariant saying that
	an empty polyhedron has a constraint system with either no rows or
	a single unsatisfiable constraint;
	- the current implementation of poly_difference_assign() is wrong in
	that it disregards equality constraints.
