Log skipped tests and test cases. These will show up as ignored tests in TeamCity.
Fix backward compatibility with python v2.6
add support for skipped tests (if python version lower than 2.7 need unittest2 for skipped tests)
Add options for python version 3
Add skipTest method to nose plugin to mask method in TeamcityTestResult.

The method in TeamcityTestResult takes a test instance and a reason, but
when nose calls skipTest on a plugin, it only passes the test instance.
So, a limitation of this solution is that the text for the reason won't
show up in the teamcity report.
