When installing Nginx, enable http_gzip_static_module by default.

It's an optional nginx module that serves precompressed versions of static files. This is useful for the Rails asset pipeline, because the asset recompilation process already generates pre compressed files. To enable it in the nginx config add the following directive: "gzip_static on;"
