Title: Misc py3k fixes; small cleanups

I've added a better error message for unsupported Pythons (issue 2619), changed the default dir used by use2to3 to py3k-sympy (so as not to mess with tab completition). I also removed some random mentions of Python 2.4 that remained (including some old and crufty files, but I didn't feel like deleting them) and deleted a script in doc/ that's no longer used (incidently, also found by searching for mentions of Python 2.4). I wanted to do a refactor of bin/use2to3 too, but as I might not have enough time for it, I'm submitting this as-is (the improved error messages are quite good).

@asmeurer, I've updated the first two patches based on your comments, but feel free to take another look at them.
