Good-lookin' diffs with diff-highlight and more

## History

`diff-so-fancy` started as [a commit in paulirish's dotfiles](https://github.com/paulirish/dotfiles/commit/6743b907ff586c28cd36e08d1e1c634e2968893e#commitcomment-13349456), which grew into a [standalone script](https://github.com/paulirish/dotfiles/blob/63cb8193b0e66cf80ab6332477f1f52c7fbb9311/bin/diff-so-fancy). Later, [@stevemao](https://github.com/stevemao) brought it into its [own repo](https://github.com/so-fancy/diff-so-fancy) (here), and gave it the room to mature. It's quickly grown into a [widely collaborative project](https://github.com/so-fancy/diff-so-fancy/graphs/contributors).
