Start of features

Guys,

it is alive my POC of this features. Now it is just a start of the tests.

What I test Is that I can create a app, a app with heroku and the first partial that is created a repo to me.

Now my personal notes on this:

- It is slow, but know what is slow run this today by hand :smile: 
- This will be running in travis later :fireworks: 
- I dont know too much about cucumber
- I create a fake heroku with thor, any comand run with `heroku` is used my heroku.
