Skip test_recommonmark/ directory if recommonmark is missing.
After basing "alltests.py" on the `unittest.defaultTestLoader`, we can (again)
skip the complete directory from the __init__.py file.
Simplify recommonmark test files (when running individually,
failing with an ImportError when recommonmark is missing is no problem).
Keep the `sys.path` setup, we still want test the local "docutils" package.
