Correct default rails environment

While the production setup is more common the default is at development here and has been for a long time, yeah. There are about three reasons for that: 1) as you said, in a production install you have to touch the configuration anyway, so that's not much of a hassle. 2) in a development install you currently don't have to touch a single setting, just copying over the file is enough and 3) Rails itself defaults to development if you don't set the RAILS_ENV environment variable.
