wkhtmltopdf web service

This web service renders posted HTML to PDF using wkhtmltopdf.

Because it allows posting of HTML content, it can be used straight from the user's browser to render the page he is currently viewing, including DOM modifications made in Javascript. It can also be used as a backend service, of course.
