Jekyll January

I’ve updated Jekyll to 3.x. Jekyll changed quite a bit of its underlying code, but mostly it was in areas that didn’t affect my site. The one exception: they changed the syntax highlighting library from pygments to rouge, which did require me to make a few tweaks to my css. I’m not entirely sure why, but it could have something to do with how I use kramdown vs. liquid tags.

If you see any problems, please raise an issue at my github page.
