Delve 0.4.2

I have published Delve 0.4.2, which fixes and a few bugs I've found since 0.4.0 was released, along with some tweaks to how much treasure is being generated, and a revamped, much more readable and usable Inventory menu.

After this, it's a push toward 0.5.0 and having content from start to the end. Ie., to have it actually be winnable, even without all the content I'd like to have in the game. I'm not going to guess at a release date for that, but it would be great to reach that before Advent of Code begins in December. Or failing that, before the new year.
