Awesome, thanks!

I have some concerns though...the FakeOCUnitTestRunner and such are still needed as xctool itself supports running both ocunit and xctests. The tests for xctool can be converted to xctests though.

Thanks for your PR. As @LegNeato mentioned we are still supporting ocunit bundles with SenTesting framework. That is why we would rename all OCUnit classes later.

I have just landed commit that moves all xctool tests to XCTest and so it makes sense to close this PR.
