Added --xetex option to pandoc and markdown2pdf.

If --xetex is specified, pandoc produces latex suitable for
processing by xelatex, and markdown2pdf uses xelatex to create
the PDF. Resolves Issue #185.

This seems better than using latex packages to detect xetex,
since not all latex installations will have these.
