Fixes for MsTest and new result file for MsTest

1. Uploaded new MsTest results example file generated from pickles-testresults project.
2. Fixed an issue with MsTest parser - previously it assumed that FeatureTitle property is the first one for a scenario and it was so with the previous testing trx file. With the new one, however, it appears that in scenario outlines a FeatureTitle property does not have to be the first property.
3. It appears that MsTest console runner supports inconclusive tests after all. The code was changed so that inconclusive tests (i.e. not ran tests) do not affect feature result (so if a feature has 3 passed tests and 1 inconclusive, the result is still passed). It already works this way in NUnit parser. Is this the right behavior?
4. A little cleanup in MsTest parser. Some duplication was eliminated and hopefully the Linq queries are a bit more readable. This can use even more cleanup - something to think about in the future.
