New TurnKey web2py version (16.0)

Changes:

• Latest upstream Web2py (via git) - v2.20.4. [ Stefan Davis ]
• Provider helper script; 'turnkey-web2py-pyver`. A script to switch running Web2py between python2 & python3. This Web2py appliance defaults to python3.
• Explcitly disable TLS<1.2 (i.e. SSLv3, TLSv1, TLSv1.1). (v15.x TurnKey releases supported TLS 1.2, but could fallback as low as TLSv1).
• Update SSL/TLS cyphers to provide "Intermediate" browser/client support (suitable for "General-purpose servers with a variety of clients, recommended for almost all systems"). As provided by Mozilla via https://ssl-config.mozilla.org/.
• Updated version of mysqltuner script - now installed as per upstream recommendation.
• Note: Please refer to turnkey-core's changelog for changes common to all appliances. Here we only describe changes specific to this appliance.
