Wagn in development

Wagn is defaulting to production mode as of Wagn 1.8.  If you want to modify wagn code, you'll want to use development mode instead.

You'll also need to install several more gems.  Go to .bundle/config and remove, at a minimum, "development" and "assets" from the "without" list.

• In general, you can use `env RAILS_ENV=development` before most commands.

• You can change back to using "development" as your default environment by commenting out the first line of config/boot.rb:

#ENV['RAILS_ENV'] ||= 'production'

(Note that it will remained commented in all git branches but master and stable).
