Testing with Aruba - An example

I've created an example of what testing with Cucumber and Aruba is like. I'm not sold. Since I had started it, I thought I'd publish it to show how Aruba behaves.

What's done:
* features/new.feature - this isn't fully implemented, it's good enough for an example
* features/brew.feature - Fully implemented, it's a full integration test from top to bottom!
* features/support/env.rb - The aruba hooks and configs
* Added dependencies to gemspec

Leaving this hear for now and switching to a straight up Rspec style using the Temp class in std library.
