New weblogs; dropping PyPI

I've started a new Blogger weblog for recording changes to planet.python.org.

As some people suggested in my PSF weblog post, I've dropped the PyPI feed because it doesn't include much information about the software being released. Personally, I also don't get much out of the PyPI entries.

New weblogs: Muharem Hrnjadovic, Rene Dudfield.
