Big refactoring adding best practices

[arojunior]

Actually, there is nothing "wrong" with your code, but it can be better. This PR is following the best practices and using another two libs to make things easier.

I hope you like it.

• Folder structure changed
• ES6 sintax improvements
• method onSubmit changed to handleSubmit (its a convention)
• handleSubmit now its an arrow function and its not needed to bind
• method handleFieldChange added, its not good to change the state from render method
• status logic changed to something simpler
• Files and login changes to organize between presentational and container components
• redux-actions added
• refactoring to redux-actions
• reducer changed to handleActions from redux-actions
• fetch-middleware added and action logic changed
• redux-thunk removed
• reducer and actions divided in two files

Hi, @Hipjea

I had forgot about this PR, thank you for to be interested.
So, it is using a pattern called "redux ducks" and you can find the explanation here: https://github.com/erikras/ducks-modular-redux#example

Let me know if I can help you with something more.
