Reformat books, use the built-in book formatting.

[Jagget]

Working with English version of the DFU I noticed poorly formatted books. Well, most of them have some artifacts.

Since SDF and non-SDF books in game respect book boundaries and hence could be auto formatted, I want to clean texts.

Nothing fancy, just

• One paragraph is one line
• No multi-spaces
• No extra empty lines.

I have to say we went for automatic text re-flowing in the french translation mod too, it feels like a more modern approach https://github.com/Daneel53/DFU-en-francais/tree/main/French%20files%20for%20DFU/Text/Books
