Title: Support include...ignore missing pursuant to #130

This should be an entirely backward compatible change.

The JtwigResource.exists() method has been introduced to allow us to determine early on whether or not a resource exists without having to load it. I added an `Include$Missing` inner class that is a blank `Renderable` as it makes operation simpler and more explicit.
