Add ability to fail whole fixture

[vincentparrett]

From G+

Is there possibility to Fail Whole Fixture.

I tired to do Assert.Fail at the
[SetupFixture]
procedure SetupFixture;

But it will kill the whole process.

This would be handy if some prerequisite is not meat the way it would need to be, then could really raise attention, that "We are not passing any of these this or that is fixed first"

Is this fixed by Issue #173 which means any [SetupFixture] error is now logged into all tests?

The only issue I can see still remaining is that despite the [SetupFixture] failing, all the tests will still run. This is not something I personally would expect.
