Specifying a tolerance with "Within" doesn't work for DateTimeOffset data types

[Peter Strøiman]

[Issue now tracked at https://github.com/nunit/nunit-framework/issues/29]

I would expect the following test to pass:

        [Test]
        public void DtoTest()
        {
            var a = DateTimeOffset.Parse("2012-01-01T12:00Z");
            var b = DateTimeOffset.Parse("2012-01-01T12:01Z");
            Assert.That(a, Is.EqualTo(b).Within(TimeSpan.FromMinutes(2)));
        }

NUnit.framework version 2.6.2.12296

NUnit currently has special code for comparing two DateTimes within a tolerance, but not for DateTimeOffset.
