* Renamed the __unicode__ methods
* Applied the python_2_unicode_compatible decorator
* Removed the StrAndUnicode mix-in that is superseded by
python_2_unicode_compatible
* Kept the __unicode__ methods in classes that specifically

This is a BACKWARDS INCOMPATIBLE CHANGE for anyone using the signal names introduced in r12223.
* If you were listening to "add", you should now listen to "post_add".
* If you were listening to "remove", you should now listen to "post_remove".
* If you were listening to "clear", you should now listen to "pre_clear".
You may also want to examine your code to see whether the "pre_add", "pre_remove" or "post_clear" would be better suited to your application.
