fix SF bug #1008690: Incorrect <link rel="index"> href in Tutorial

The make_head_and_body() function used a hardcoded value for the
<link> element for the index; this patch causes the proper output
filename to be captured during the transformation phase so it can be
used during the page assembly phase.
