Recolor all books systematically (second try)

After https://github.com/CleverRaven/Cataclysm-DDA/pull/7461 was rejected by many and after a discussion here <http://smf.cataclysmdda.com/index.php?topic=6289.0> I worked out a new recoloring of the books. This time it is not overly technical. See the original pull request for details.

Color code:
* Magazines: pink
* “Paperbacks” Short enjoyment books (including novels): light cyan (surprisingly there are only 3 of those. Maybe that’s something to keep in mind for the future. The vast majority of novels has way more than 10 chapters. I keep this category for now, it doesn’t hurt.)
* “Hardbacks” Long enjoyment books (including novels): light blue
* “Small textbook” Beginner level textbooks and guides: dark green
* “Large textbook” Advanced level textbooks and advanced guides: dark blue
* Religious books: dark gray
* “Printouts” (including spiral-bound and similar) Technical documents, (technical?) protocols, (lab) journals: light green
* Other reading material/non-books (used only if every other category does not apply): light gray
