Support and documentation for Oscar 3.0

Now the Django Oscar 3.0.0 is out in stable I’m trying to implement PayPal payments. The tips given in #216 were helpful, yet I’d need some help. The payment method isn’t recognized by Oscar in the checkout/payment options step, which suggests installing one of the 4 payment gateways (along with Adyen, Docdata and Accounts). I’m clearly missing something.

OSCAR_MAIN_TEMPLATE_DIR setting has been removed in Oscar 2.0. My template oscar/basket/partials/basket_content.html should be loaded as it extends the Oscar’s one ({% extends 'oscar/basket/partials/basket_content.html' %}), but it isn’t.

Also, Oscar 3.0 uses Font Awesome icons, so now the Dashboard menu entry will get its icon with 'icon': 'fas fa-globe',

In my own view, the oscar developers should consider implementing one of the payment methods like paypal by default so that developers can just reuse the code when implementing other methods.
