revamp configuration with Configurator DSL

The Configurator includes error checking and opens the way for
better reloading/error-checking abilities.

This also renames many of the config settings with something
nginx-like to minimize the learning/setup curve since nginx is
the only recommended reverse-proxy for this.

s/pid_file/pid/
  => blech!, more confusing :<

s/listen_backlog/backlog/
  => maybe more confusing to some, or less...

s/nr_workers/worker_processes/
  => less confusing to non-AWKers for sure

s/hot_config_file/config_file/
  => the config file is now general purpose,
     not just hot reloads
