Added Blogging Pompeii to Maia Atlantis

I don't know how it's possible that I've been unaware of the Blogging Pompeii blog all this time. Thanks to a post on the ever-vigilant David Meadows' Rogue Classicism blog, my cluelessness has been rectified. And of course I've added Blogging Pompeii's feed to the Maia Atlantis aggregator.
