production.default.props does not resolve #1

Hi David,

I'm using Dragonmark Utils in my Clojure side project (the get a bit of Lift feeling :) ).

The doc string says production.default.props would resolve as the default production property file. However that would only resolve if I set -Drun.mode=production, but this isn't recognized as production run mode.

To make it work I set -Drun.mode=prod and name the file prod.default.props.

To make it consistent, either the documentation should be adapted or :production be added to the run modes that trigger production-mode?
