Title: Ignore nil nodes in hickory-to-html

This is a small change to make it so that hickory-to-html doesn't fail on `nil`. Lots of Clojure functions tend to return nil in various scenarios, and I think it makes sense to handle `nil`s rather than throw an exception on them. It's also useful to me because it makes it easy to 'remove' nodes in a hickory zipper without using `zip/remove` and instead replacing them with `nil`, since I'm doing a postorder walk and `zip/remove` jumps to the next node in a depth-first walk.
