Adds headings for methods in the output of `ls` command of Pry. It was rejected, because for most people it looks unpleasant.

Running a Cinch IRC bot on Heroku (by zobar)
  1. Add Heroku to your Gemfile and bundle install.
  2. Create your Heroku app. This will only work with their (currently-beta) 'cedar' stack, so you have to heroku create --stack=cedar.
  3. Create a Procfile for your bot. This tells Heroku how to run your worker. In our case, the bot is bot.rb, so the only line in the Procfile is cinch: bundle exec ./bot.rb
  4. Commit and push to Heroku.
  5. You do not want a Web worker running, so heroku scale web=0 cinch=1. This also sets up your deployments to restart the bot.
