Node body shouldn't be required; title rethink

While I can comprehend the use of nodes as a shortcut for meta-data like expiration times and so forth, "describing" a feed isn't entirely useful - thus, requiring the Body element is a pain in the ass (just what do you put in there when you've got 320 feeds to import? Which, I do.). Similarly, I'm not entirely enthused that the title of the node won't represent the title of the feed - I don't see why I have to manually update the title when the feed provides that (and the description too) for me automatically (this is also a failing of aggregator.module).
