Right now the delegates' inline hover buttons can be very difficult to see, because they're
(mostly) white and don't get much background contrast. A gradient appears on the bottom of
the thumbnail on hover, which provides a bit of visual differentiation, but no real contrast.
This patch improves the situation by replacing the current gradient with a darker
semi-transparent solid color. In addition to improving contrast for the buttons, I
think it also just in general looks nicer than the bottom gradient.
