Added Bens new graphics

I added Bens new thumbs up/down and RSS graphics. They look AWESOME. I also added tooltips to some of the elements on the main page, mostly to see how well they work. I also use the tool tips on the display pages to describe about the thumbs up/down buttons. I stopped displaying the total number of votes. This is easy enough to stick back in when we want to.

I think that I am going to vote right now that Ben create little square buttons just like these for email/contact/Flag/Facebook and Digg;-)

More to come...
