Atom Support fixed

In the last build of BottomFeeder, I accidentally broke support for Atom 0.3 feeds. I was adding support for the putative Atom 1.0 standard, and factored my code badly - thus breaking Atom 0.3 feeds in Bf. I've got an update available - grab the latest BottomFeeder.pcl if you haven't been seeing updates to feeds that you should have been. I'm also replacing the full builds on the download site, since they had this flaw baked in.
