Bug #25 : Done. If there is an environment.json file defined in the base app directory, then the App will use the values provided in that file. Otherwise, it will use the Model's defaults. The model should be set to production values; that way, if there's ever an accident with the environment file, the worst that will happen is that your devs will set up a prod environment, rather than your prod boxes using development settings.

Also fixed a bug with the new dynamic multi-routes-per-callback system.
