Make our temp file mixin unittest-friendly....

Make our temp file mixin unittest-friendly. This does not break any nose compatibility, but it lets us use our mixin with normal unittest.TestCase objects in addition to nose-oriented tests. We're trying to lower our dependency on specifics of the nose api, so that in the future we might be able to run without nose at all (as unittest improves).
