Consider dropping the dependency on the countries gem and using a YAML file instead

[monfresh]

From what I can tell, the only thing you need the countries gem for is for the country_code numerical value. I just ran a memory benchmark on my app using the derailed_benchmarks gem, and phony_rails is by far the biggest consumer of memory at around 25MB. Most of that is coming from the countries gem, which in turn comes from the currencies gem. I've asked the countries gem maintainer to consider removing currencies as a dependency since not everyone will need it. For example, phony_rails doesn't need it, but it still gets required and consumes memory.

Since all you need is a list of numerical country codes, I propose that you create a YAML file based on the ones in the countries gem, but with only the country_code field.

Thoughts? I'd be happy to submit a PR.
