feature: Generate a spec file.

[schwern]

Unlike schema migrations, data migrations are easy to test but require a bit of special setup. This adds a spec file to the generator.

• Loads the migration.
• Sets up the a quiet migrator object.
• Basic describe up/down blocks with subjects.

Closes #148

Good idea. However, what about the people who don't use rspec? Maybe there should be an env var or something that is set if you want to generate spec file? I there there is something in Rails itself about this, but don't remember exactly how it works there

Rails.configuration.generators.options[:rails] can be introspected to get the test_framework. I'll see about putting something together for minitest.

Cool. That's a great idea

Sure. I'll have to reload it into my brain.
