Subject: [PATCH] org-latex.el: New defcustom `org-export-latex-quotes' to
 control quotes.

* org-latex.el (org-export-latex-quotes): New defcustom.
(org-export-latex-quotation-marks): Use it.

This allows users to define what quotes they want to use as a
replacement of english double-quotes while exporting to LaTeX.

In particular, if you use the csquote package, you can configure
Org to output something like \endquote{some quoted text} instead
of "some quoted text".

Thanks to Frederik for bringing this issue up, and to Thomas S.
Dye, Nick Dokos and Stefan Nobis for elaborating this solution.
