Add block form to Nenv() helper method

[monkbroc]

I added a Ruby-ism to allow using the Nenv(:namespace) helper in block form. It avoids creating a local variable, but mostly I like the way it looks.

Here's how I use it in my application:

Nenv :filepicker do |fp|
  Rails.application.config.filepicker_rails.api_key = fp.api_key
  Rails.application.config.filepicker_rails.cdn_host = "https://#{fp.cdn}"
end

Absolutely beautiful PR request!

Coverage increased (+0.88%) when pulling f47d908 on monkbroc:namespace-block-form into 58ce856 on e2:master.

Thanks! I love the gem. I have been feeling a wrongness about having to check for == 'true' or == 'yes' against environment variables. Very non-Ruby. Nice work coming up with a beautiful DSL!

I like this so much I released 0.2.0. Thanks so much again!
