Some 'engine' work for v0.7.7 (Patreon)

Thought I'd write a little about what I've been doing over the weekend. Resolved some of the annoyances I had with the way the game was coded, namely I've added the following things:

1. A "≪" link that goes back to the previous choice, not scene. You can click on this link with your mouse, or press the "←"  key.

2. A "⋘" button that goes back a scene, and a "⌂" button that goes back to the home screen.

3. A "save to disk (🗀)" option, if you want to save your progress while playing in a private-browsing window. And of course an option to load said save on the home screen.

4. A pop-up screen that shows when you hover over the scene information, allowing you to see the exact place you are in, code wise. Useful for debugging.

Are there any other things you miss, 'engine' wise? Let me know, and I can try to think of a way to implement them.
