PDF slides are not all exported

[cmoulliard]

This issue is due that we don't pass the revealjs folder in this script

<!-- If the query includes 'print-pdf', include the PDF print sheet -->
<script>
    if( window.location.search.match( /print-pdf/gi ) ) {
        var link = document.createElement( 'link' );
        link.rel = 'stylesheet';
        link.type = 'text/css';
        link.href = 'css/print/pdf.css';
        document.getElementsByTagName( 'head' )[0].appendChild( link );
    }
</script>

Should be

<!-- If the query includes 'print-pdf', include the PDF print sheet -->
<script>
    if( window.location.search.match( /print-pdf/gi ) ) {
        var link = document.createElement( 'link' );
        link.rel = 'stylesheet';
        link.type = 'text/css';
        link.href = 'revealjs/css/print/pdf.css';
        document.getElementsByTagName( 'head' )[0].appendChild( link );
    }
</script>
