Fix to bug where 'Select Product' is shown. Fix to flash of default select element, it must be hidden with CSS. JS is slow.

Wrap methods of payment list in the conditional.
Collection placeholder captions were huge on home page. Using same markup as for product placeholders now.
Use text-center consistently - is used for collection caption but not products.
Minor comment update
Add class js to HTML on load
product-page specific css to show/hide product variant select dropdown
CSS-first hiding of product variant dropdown. No-js will show it again
