Title: Make slideshows keyboard accessible

Hello, here's a quick pull request for issue #1001. As suggested in that thread I have set the slideshow controls to default to `opacity: 0.5` rather that `display: none`. The controls fade to full opacity on focus or hover, and I have added checks so that they won't fade back to 0.5 as long as either the mouse is over the slideshow or the controls are focused.
