Cart/Category page Updates

- Cart: Updated product layout to look more uniformed. The previous
layout allowed longer named products to wrap longer text underneath the
image, breaking uniformity.
- Cart: Added calculate and update buttons to the shipping and quantity
input boxes to signify to a customer that may be confused what to do
after updating these inputs. Auto-update functions still active.
- Category page: Made several adjustments to the 2 column category page
template to make it better reflect Jeffs requests.
