INFRA-193 docs.civicrm.org should display current version's home page
docs.civicrm.org currently displays a sparse landing page that was probably intended to have links to the manuals for different versions of CiviCRM or different products.
Please have docs.civicrm.org land at http://docs.civicrm.org/user/en/latest/ instead.
