Microsoft Test Manager: Customization of test result fields and marking test results as NA

Introduced the ability to customize test result analysis fields like 'Resolution' and 'Failure type' in Microsoft Test Manager (MTM) and the TEST hub in TFS web access. Also introduced a new test outcome state called 'Not applicable' for marking test results in MTM or the TEST hub when test cases are not relevant to the current test pass or refer to unimplemented areas.
