Moved from EJS to Jade

Well, here is one that I certainly understand if you decide to pass upon and I spent way too much time on it anyway. But, since 'ejs-locals' is no loner maintained by its author and EJS seems to be less popular than Jade, I went ahead and moved the example over to Jade from EJS. Like I said, I certainly understand if you don't want this one given that I'm starting to drift further from Jared Hanson's original pre-Express 4 examples. But, at least it saves ten lines of code and moves over to Jade.
