Subject: [PATCH] docs: Remove XSLT table of contents generator
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The only remaining page was 'hvsupport.html' which is generated by
'scripts/hvsupport.py'. The script already has all the data to generate
the table of contents internally so we can remove the whole complicated
template.
