Add Jasmine to the project

So we can test JS now.
Remove users and orders controller

As we're dealing with subscriptions, I realized that the 'Order' and
'User' weren't the right names to use.
Moved users to subscribers controller (we can have a users controller,
but for users) and subscriptions (not orders), after all, the users are
subscribing, not buying.
Ignoring the env variable initializer at config/initializers/
Change the style of the 'select plan' on the subscription form
Fix route and association name

Before it was supporters, now it's subscribers.
Fix all association names

Change order model to subscription model, move views and add
constraints on the database as well. A rake db:migrate should do the
rest.
Initialize moip using a env VAR
Add subscribers form and subscriptions controller

In the subscriptions controller, add project and subscriber relations
to the create action. In the form, just small fixes. Also add view
thank-you to show after a user has made his subscription.
Create subscribers controller

Create controller that has a User model as resource. Also, add logic
behavior: if the user has already signed up, with his email and cpf,
don't throw a error.
Also add the 'thanks' action - which verifies if the user has
subscribed; if not, just go home.

TODO: fix the belongs to (it's not working anymore) and remove those
ugly lines from the create method.
Add subscription error message element and small fixes on the subscription form

We render error messages inside the #subscription_error_message element.
Also, show only numbers on the month select; add data-token to the form
(instead of having it on a meta tag) and add the real subscriptions
fields as hidden fields (so we can detach the others and send the form).
Add function to remove non numerical characters

Remove non-numerical from the user form, like zipcode, cpf and so on.
Also, make expiration year just returns the last 2 numbers, instead of
the whole year number.
Change how the moip token is captured, add error_message

Now it's captured from the subscription form as data-token. Also, print
errors inside the subscription_error_message div.
Check if we got the zipcode info from the server

If not, do nothing.
Add Bind data from event and add to the subscription form its true url
Add SaveSubscription function

Also, make the moip token be used as parameter on the
CreateSubscription function.
This function detach the entire non-hidden fields from the form, so we
can submit it without much pain.

Also, bind the click submit event - not the submit one - from the
subscription form
Fix specs and blueprints used on tests

Also add jasmine.yml file.
