importing advogato entries to pyblosxom

here is a version of Thomas's advogeto script to make it output the advogato entries with filenames in the date format used by pyblosxom's plugin. And, because I can't get that plugin to work properly, here is a script to set the date of those files to the date in their filenames. That's useful when I mess up the dates on my files, avoiding hundreds of entries on one day.

Python isn't my speciality, so don't blame me for the ugly code.
