Update Social Icons to Use sharingbuttons.io
Summary
I stumbled upon this site one day on hacker news and I think it'd be nice to replace our current social link buttons with these. Let's see what happens, it may look ugly on Go but if we don't try then we'll never know. You'll need to look at including the generated css into it's own .css file and have the HTML update the href link for every Go link. You can use Django templating for the latter. But yeah: copy the css, copy the HTML, modify the href tag to be dynamic.
Starting point is link_box.html
