Here's an update where I've started some work on the bottom pane.
It's still going to need some serious love, but some of the idea's in
Jamie's Sep 14 email are starting to be incorporated.
Oh..and I got rid of setting the layout and max results by environment
variable...not sure why I did that...any way, now they are command
line arguments, and their form is "--layout=2" and "--max-hits=50".

Thanks - They all look good in their own way!
