Title:
  Improve DateTime equality assertions to include DateTimeKind

Status in NUnit V2 Test Framework:
  Triaged

Bug description:
  The following test will fail, even if the two DateTime structs are not equal.
  (I know it's because the equality members of the DateTime type does the evaluation which doesn't care of the Kind property)

  [Test]
  public void Foo()
  {
      var localDate = new DateTime(2013, 04, 24, 13, 17, 44, 678, DateTimeKind.Local);
      var systemDate = new DateTime(2013, 04, 24, 13, 17, 44, 678, DateTimeKind.Utc);

      Assert.AreNotEqual(localDate, systemDate);
  }

  But I always extracts my assertions to a helper method which also
  checks the Kind property.

  public static class AssertX
  {
      public static void AreEqual(DateTime expected, DateTime actual)
      {
          Assert.AreEqual(expected, actual);
          Assert.AreEqual(expected.Kind, actual.Kind);
      }
  }

  I would like to have NUnit help me with this instead of always calling
  my own helper class.

  However, I'm not sure how this best could be implemented in NUnit.
  A simple overload of AreEqual(object, object) to AreEqual(DateTime, DateTime) risk breaking compability with existing tests out there.

  One way would be to instead use another name, Assert.Identical or
  similar.
