Title: Fix Python 3.3 issues

In this pull request I will fix any Python 3.3 issues that I can. Feel free to review and merge this at any time. I likely won't be able to figure out all the problems, so any assistance would be appreciated. In particular, I have no idea how to approach the doctest failure.

See [issue 3272](http://code.google.com/p/sympy/issues/detail?id=3272).
