* Upgrade to the newest six module (1.2.0) and call it six instead of wx2to3.

* Tweak six a little, adding its license text since we'll only be distributing the module, fix the name of the dummy moves module, and add a PY33 constant since the change in memoryview affects our code.

* Update all modules already using the old wx2to3

* Tweak lots of unit tests and other modules to work with Python 3.3 (still a few more that will need some work.)

* Try to deal with memoryview changes in Py3.3, without much luck...
