Move the top level html pages into the ocata directory and establish
redirects for their new locations.
Recover the old versions of the project list and language-bindings
pages with their static lists and use those for the ocata pages. We
will use the dynamic templates for pike and later series.
Bring the included templates inline in index.html to adjust the links
they provide without breaking other pages.
