Changes between 2.2.0 and 2.2.1

• fix issue99 (in pytest and py) internallerrors with resultlog now produce better output - fixed by normalizing pytest_internalerror input arguments.
• fix issue97 / traceback issues (in pytest and py) improve traceback output in conjunction with jinja2 and cython which hack tracebacks
• fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns": the final test in a test node will now run its teardown directly instead of waiting for the end of the session. Thanks Dave Hunt for the good reporting and feedback. The pytest_runtest_protocol as well as the pytest_runtest_teardown hooks now have "nextitem" available which will be None indicating the end of the test run.
• fix collection crash due to unknown-source collected items, thanks to Ralf Schmitt (fixed by depending on a more recent pylib)
