Develpment of the application, so far, so good.

This is the work I've been doing for the past days, the app's CRUD is now working and I added bootstrap so it doesn't look so bad. There's some stuff missing yet and I'll working on it (hopefully I'll finish most of it today): 

*~~Interfaces (the basic ones are done, working on making them better looking and adding missing ones)~~  Done.
*Validations on the models.
*RSpec tests.

I'm not listing the Capybara tests because I'm not sure if I'll finish them on time.

After I'm done with the validations I'll make another pull request.
