Title: Use publish_date for BlogPosts in /sitemap.xml

Since BlogPosts most probably won't change much after they have been created, we could use the publish_date attribute as the Last Change date for the generated sitemap.

It would be cool to have this also for Pages but I'm not sure publish_date makes sense on pages since it might be not unusual that pages are updated after their publish_date.
An additional update_date attribute would be cool which could be updated automatically on each save() or so. But this is quite a heavy change just to have a date in the generated sitemap, so I don't propose that unless there might be other valid uses.
