deff - an interactive, side-by-side file review for git diffs with per-file navigation, vertical and horizontal scrolling, syntax highlighting

Using the github UI I always find it hard to review big PRs exceeding several thousand lines of code. Maybe a different viewer is helpful. Taking recommendations here.

@spinscale I don't know Deff so maybe it does something that IntelliJ doesn't do, or maybe you mean for use outside IntelliJ, but I find it works well for big changes. Some folks use the GitHub integration for the actual review process (inline comments etc).
