I suspect the DirtChest9000 was added as a joke, but there are genuinely many cases where a single-stack inventory would be really handy. This almost serves that need but sadly it's restricted to dirt only.

1. It would be nice if the DirtChest (or perhaps a separate chest block) would accept a single stack of any item.

2. In 1.10.2-7.0.11.797 at least, the book that comes with the DirtChest9000 is broken -- it only displays the first word on each page.
