Title: Fix UserDict import for Python 3 support

As mentioned in #192, UserDict module doesn't exist in Python 3. Instead, collections.MutableMapping is imported in that environment. As this is just a fix for Python 3, no additional test included. Let me know if I should change something about that. Build passed at https://travis-ci.org/pswaminathan/flask-restful/builds/24404614.

Thanks!
