Transition to NGINX

1. Initial testing strategy is to move nginx to port 80, and proxy everything to Apache on port 8090 -- creating a shim.
2. Without PHP available via FastCGI, any function at all for PHP-based applications validates NGINX.
3. Current state (2020-01-11)
   1. Principal functions migrated to NGINX
      • Admin Console (http://box.lan/admin)
      • kalite -- goes directly to port 8009

      • usb-lib
   2. Dual support
      • awstats

      • kiwix -- goes directly to port 3000
