use nginx to validate config

validate_conf.sh

#!/bin/bash

#
#  validate nginx config
#
#  depends upon a symbolic link from /var/apps/redirector to dist directory
#  and a build of nginx which supports real_ip and other extensions
#
#  probably best to build a chroot'd tree containing a complete nginx server
#  though that's a lot of work to copy in shared libraries, etc
