Convert any Ruby object into a Python string (for ERB templates in Chef)

pybool.rb

class Object
  def to_py_bool
    (!!self).to_s.capitalize
  end
end

Guess I'll add this comment here instead of my closed PR:

Maybe I'm crazy, but ! is the boolean negation operator in ruby, right? So why call !!self instead of just self?

So !self returns the opposite either TrueClass or FalseClass as the literal class based on Ruby's true/false rules (meaning anything except 0, nil, and false returns true). !!self returns the original TrueClass or FalseClass as the literal class. From there you can be guaranteed that the thing that you're .to_sing is going to be the actual String "true" or "false".

So what you're saying is that after adding this, we can further obscure our attributes by assigning them differing non-boolean values, and yet they will all end up as the right thing. +1!
