v0.12.123: @newsroom.writer: wishes, not demands

Softer "I want". Dinis asked for the abstract of a website to finish the book to stop opening with "I want a website for it": it reads as a demand, and it is not how he speaks. It now reads "the plan is a website for it".

The same phrasing is softened across the articles in his voice: 35 articles and 68 places, plus five section summaries. "I want" becomes "I would like", "the idea is", "the plan is", "I hope" or "what I have in mind", depending on the sentence.

"I want" stays where it is plain description rather than a request: "when I want to read a post", "the people I want to help", "being able to compile a Linux kernel does not mean I want to". The title I just want to buy the article stays too.

The article guide gains a voice rule, Wishes, not demands, so new articles start that way. Each changed article keeps its earlier version on its version page.
