Reddit Preview Button Fix

Some custom CSS on old.reddit.com causes the expand button to glitch out (where there's supposed to be a button, there's a gibberish image instead). This style fixes this by replacing the buttons with new button images from the Silk icon set. (https://commons.wikimedia.org/wiki/Silk_icons)
