assert.notEqual passes when 2 different objects have the same values

[astorije]

The following test fails (see this build):

var list3 = List.of(1, 2, 3);
var deepMap = new Map({ foo: 'bar', list: List.of(1, 2, 3) });
var sameDeepMap = new Map({ foo: 'bar', list: List.of(1, 2, 3) });

it('should fail given equal values', function () {
  assert.throws(function () { assert.notEqual(list3, List.of(1, 2, 3)); }, Error);
});

it('should fail given deeply equal values', function () {
  assert.throws(function () { assert.notEqual(deepMap, sameDeepMap); }, Error);
});

This shows that assert.notEqual needs to be overriden to take into account equality between values even though the underlying objects are different.
