Hi there,
this patch adds a docs badge to the README to show off inline-documentation to potential contributors: 
The badge links to Inch CI, a project that tries to raise the visibility of inline-docs to encourage aspiring Rubyists to document their code. Your status page is http://inch-ci.org/github/stripe/pagerbot/
Inch CI is still in its infancy (3 months old), but already used by projects like Bundler, Guard, Haml, Pry, and ROM.
What do you think?
