The default citation capability of LaTeX is not a true numerical
citation engine, rather it uses a mixture of labels/numbers. Thus
we now distinguish them: "numerical" always increments the bibitem
counter and uses its value as a numerical citation label, while
"default" only uses the bibitem counter when no label is provided.
LyX file format incremented to 471.
Add a new layout syntax CiteEngine to define the citation commands
available for a given citation engine.
Also extend the CiteFormat syntax to allow more customization. This
mechanism, previously used to produce bibliography entries in the
citation GUI based on the BibTeX entrytype, is now also used to
produce the textual labels for citation insets in the buffer view.
Thus citation styles are almost completely customizable by modules.
Modules for the basic, jurabib and natbib engines are implemented.
Layout format incremented to 37.

To avoid duplicity, remove natbib_authoryear and natbib_numerical
and replace them by natbib, and keep track of the engine `type'
in the new \cite_engine_type document setting. This will make it
easier to add more citation engines.
LyX format incremented to 424.
