Mike Hall's Denote setup

Mike Hall is on a roll with his Denote setup. I'm following it all closely because I use a nearly identical set of tooling, except mine is not nearly as well thought out or complete as his. His latest adjustment is around org-gtd and Things. I've been using org-gtd for a week or so and I'm also not sure it'll stick. Mike created a nice way to generate links between Denote notes and Things.
