Greed 2: More widgets

While I'm on a kick to write widgets, both at home and at work, I thought I would put a couple more of them in Greed.

Both of the new widgets fall into the "large" category. One of them shows the latest article title and a short summary of the article. The other one shows a list of the article titles in the feed/label/state you've selected for the feed.

I also changed the background for the widgets to something simpler and cleaner. There's no "Greed" icon in the top left of the widgets anymore, but I kind of like the fact that they're cleaner looking and sort of transparent.
