Added 'paper' after $papersize$ variable in latex template.

Thus you can say `papersize: a4` and the latex will contain
`a4paper`.

This change may break some existing workflows; if you currently
specify `a4paper`, you'll get `a4paperpaper` which is meaningless.

However, the change seems worth it, as it will make the
`papersize` variable work uniformly across ConTeXt, LaTeX,
and html->pdf via wkhtmltopdf.
