Dark Mode for Story View

[spaceninja]

First of all, thank you for adding Dark Mode! The ability to have a dark theme for the code and the Index have been really helpful, since I do most of my Inform work after hours.

I was wondering if it would be possible to also invert the colors on the Story view when in dark mode? It's quite jarring to compile the story and suddenly get a big glaring white panel.

(I have the same question for the documentation view, but I assume that's trickier, and I can work around it by hitting the website and using a browser plugin to force a dark mode.)
