Unmaintained vB4 Importer 3.6b2

Adam posted a copy of the previous vB4 importer that he used to maintain so I am uploading it as the current version. This version is more up-to-date and fully featured than the old one I posted before. It imports everything including social groups, user albums, blogs, and CMS articles. Since XF doesn't have those features it imports them as threads / attachments.
