Hi,

This patch does two things.

     1. Add better format-spec to ox-latex hyperref and title-command.
     2. Use this to extend basic hyperref formatting to include title,
        author, language etc.

Wrt the title-command, this is useful if you need one-off "custom"
formatting of a header in LaTeX, e.g. in ox-publish projects.
