Generalize to support organization from config

[dsalahutdinov]

Hi!

What do you think about an idea to make organization name customizable.
In this way the project would be ready to use by everyone who wants, just changing default
organization name from "hanami" to other (for "rails" 😄 ) to analyze contributions

Here is the first step for doing this #35
