Add HWIOauthBundle to deps
Allow Variant selection for Products without Options

Currently a bunch of code assumes that a product only has variants if it has options,
even though what really matters is whether there are variants.
This PR checks for the presence of variants instead of options.
Display Product Variant consistently in cart, checkout, order receipt.

Currently there are 3 frontend areas where a product variant is displayed in 3 slightly different ways.
This PR centralizes display logic into one template and simplifies the other templates.
