Generating a bibliography

[Omikhleia]

SILE 0.14.17 / 0.15-develop

The bibliography packages doesn't offer a way to generate a bibliography from cited works.

While one can achieve it by calling \reference for all cited works, this is tedious and sub-optimal. So we would need a \bibliography command.

Here is my first take at the topic:

• The \cite command should keep track of cited works in a scratch list
• The \reference command should have an option to suppress the author, replaced by an horizontal rule (see rationale below) Removed: This only makes sense in the context of the bibliography. The \reference command wouldn't make sense eventually. (If you want a full ref. to a book, use a citation styles that uses that for citations).
• A \bibliography command should be implemented
  1. Sort all entries (by default, by "author-date") with appropriate SU.collatedSort on names, then by date.
  2. Call the \reference logic on the sorted list, with author suppressed if identical to the previous one (i.e. replaced by a rule)
  3. Clear the scratch list of cited works, so later use (in a different chapter or whatever) start afresh.

Regarding:

Sort all entries (by default, by "author-date")

Of course, CSL also defines how to sort entries (cs:sort) in a given style...

Edited the description.

On the use of SU.collatedSort see #2105 -- but we can do without it for now (with a workaround), and implement the base logic.
