Tweaks branch: Author name and book title display format made independent from sorting

[At-Libitum]

See 184ca88, 4dce0c1, 9c7329d and 37f9760

Changed author names function to always bring back both the regular form and sort form so that sorting could be done independent from the preferred display format, and did the same for the book title.

Changed various references to author name to make sure they referenced correct variable.

Changed output processing so that both forms are always present whenever needed.

Adjusted html template and stylesheets to account for both forms being present in output and to make sure that one form stays hidden where both forms are present (on book list and on book detail pages).
