Changed XHTML1 source generation

Changed previous recommendation header

Now Matches best practice according to W3C pubs.  Uses 'Recommendation'
instead of 'recommendation' and shows 'Previous Recommendation' if
status is REC and there was a previous REC.  These changes at the
request of Ivan Herman and backed up by evidence in a non-ReSpec
produced recent W3C Recommendation at
http://www.w3.org/TR/2013/REC-rdf-sparql-XMLres-20130321/
Fixed tests to recognize new header content.
Reset Latest header based upon feedback.
