Fixed `engine-add-writer!' so that the insertion order is kept.
* src/guile/skribilo/engine.scm (engine-add-writer!): Use `append'
instead of `cons' when adding a writer, so that the insertion order is
honored when lookups are performed. This fixes a generation bug (e.g.,
for the first page of the User Manual) and slightly improves
performance.
* src/guile/skribilo/writer.scm (lookup-markup-writer): Documented the
impact of registration order.
