v0.30.0 Day and night cycle

This version introduces a day and night cycle that can be further expanded through listeners. For example, want something to turn into a werewolf at night? Now you can do that (through coding, of course).
Built in is the LLM describing the transition.

As the sun dips below the horizon, casting long shadows across the room, the once vibrant colors of the living space gradually mute into softer, more subdued tones, signaling the peaceful transition from day to dusk. The warm glow of the afternoon light slowly fades away, replaced by an ethereal twilight that bathes everything in a soft, golden luminosity.

To use this in a story, open story_config.json and add day_night = true
I should also mention one other option that is relevant:
gametime_to_realtime how much faster time in game passes than real time. Defaults to 1.

I also fixed a long in the making feature that shows the images of present NPCs on top of the room image.
