Checkpoint. Manipulated things so that string literals are always unicode, and a few other compensating changes, e.g. str <- unicode, chr <- unichr, and repr() of a unicode string no longer starts with 'u'. Lots of unit tests are broken, but some basic things work, in particular distutils works so the extensions can be built, and test_builtin.py works.
