Message 213389 - Python tracker

Not sure how much I'll be online tomorrow or Saturday, so I went ahead and committed what I had.

The new guides definitely aren't perfect, but I think they're in acceptable shape for 3.4.0, and we can improve them in parallel with Python Packaging User Guide updates (e.g. there were some "How do I...?" questions I left unanswered because the relevant PPUG sections don't have answers yet. In particular, I completely punted on the non-PyPI distribution question for now)
