Docs are incomplete?

To get djangoshop-stripe working, I had to create myproject/templates/myproject/checkout/payment-method-form.html with the following content:

<form shop-dialog-form name="{{ payment_method_form.form_name }}" novalidate>
    {{ payment_method_form.as_div }}
</form>
{% if payment_modifiers.stripe_payment %}
    {% include "myproject/checkout/stripe-creditcard-form.html" %}
{% endif %}

Also, djangoshop-stripe must be added to INSTALLED_APPS.

We must update the docs.

To prevent future users of django-SHOP running into the same problem, his HTML snippet now is part of the original template shop/checkout/payment-method-form.html.

The docs already state:

Add ``'shop_stripe'`` to ``INSTALLED_APPS``.

I think we should still update the README for djangoshop-stripe, to help users who are not running the latest django-shop version.
