I'm on a project where I'm packaging a war on machine X for environment E. Machine X doesn't have access to the database
in environment E. (The app will be deployed to a machine Y that does).

The attached patch makes it possible to omit the :environment rake task like this:

Warbler::Config.new do |config|
  config.use_rails
end

The same is possible for Merb:

Warbler::Config.new do |config|
  config.use_merb
end

Cheers,
Aslak
