Improve Jenkins Builds in the Commander

[darnjo]

There are certain changes needed to make the Commander more Jenkins friendly:

• Use scenario.write to log information about what was found rather than logging to standard error.
• When Data Dictionary tests fail, the code to remove the skipped tests to make the reports pretty for Jenkins and Cucumber doesn't run and those using Jenkins see both skipped tests and failed tests in this case. Since the number of tests in the DD is large, skipped tests need to be removed in the error case as well.
