Disable phone-home to api.qloapps.com

Add _QLO_DISABLE_PHONE_HOME_ (default true) and honour it in
Tools::addonsRequest(), Tools::refresh(), the installer notification and
the theme catalog fetch. This stops sending admin name/email, shop domain
and country on install, the daily upgrade check, the admin
"recommendation" HTML and module/theme catalog requests.
Language and localization pack downloads stay available.
