Crystal Orb 0.2.5.1

Crystal Orb 0.2.5.1 has a bunch of bugfixes, and I'm experimenting with new placeholder images. These are not too important, since it's a text adventure, but it's 2023 and we now have ways of quickly producing lots of placeholder graphics. I appreciate there is now a mix of different art styles in the game (characters and monsters are "svg-style" silhouettes, regions are pixel art landscapes, locations are isometric pixel art), but I don't care.

I'll now work on more quests, more exploration challenges, things to do at Important Places if you find them. Hmm... nighttime should be more dangerous, don't you think?
