News You Can Bruise for 2003 January 1

Did some NewsBruiser code cleanup, and added a MailImporter class which will take an email message and turn it into a NewsBruiser entry. It will handle attachments to the email as uploaded files. There's also a less-polished RSSImporter class which imports entries obtained through an RSS file (right now it only supports RSS 3.0). I'm making RSS the official import/export format of NewsBruiser; it works well for that and I don't want to come up with something else.
