Subject: Lout engine: Make URLs breakable; make bibliography defaults sane.

* src/guile/skribilo/engine/lout.scm (lout-split-external-link): Use
  `!lout' and `lout-make-url-breakable'.
  (lout-make-url-breakable): New, taken from `url-ref'.
  (url-ref): Use it.
  (&bib-entry-title): Don't issue bold text.
  (&bib-entry-url): Likewise.
