META: Yet more tweaking

Tonight I added two slightly nifty features to the ol' blog. First, I added a "current contest" widget in the right side bar that will (duh) show you whatever contest is the current one. I bet you could not have figured that out had I not said it so forthrightly.

Second, the "Sketch of the Day" category now shows you the actual images instead of just the list of headlines. It's the same thing I did for the "Hall of Fame" category a few days ago.
