diffrent 0.2.0

Diffrent is a very simple way to do ActiveRecord version diffing. It provides a convenient interface to two other libraries ([Diffy](https://github.com/samg/diffy) and [Vestal Versions](https://github.com/laserlemon/vestal_versions)), combining their functionality. It makes no assumption about what web framework you're using - it can be used in Sinatra, Padrino, Rails, or with no framework at all.
