this patch adds a docs badge to the README to show off inline-documentation to the casual visitor: (and hopefully inspire them to write inline-docs as good as these)
The badge links to Inch Pages, a project that tries to raise the visibility of documentation in Ruby projects. The status page for Commander is http://inch-pages.github.io/github/visionmedia/commander/
Inch Pages is still in it's infancy, but already used by projects like Guard, Pry, and Libnotify.
What do you think?
