Add number input & button to product list to add a product to the cart

[valincius]

On the products page, replace the "Purchase" button with "Add to cart" button along with a number to change the quantity that we're adding to our cart.

To clarify, is the expectation for this issue to simply change the text on the button and add a number input for quantity, or is it also implied that the functionality be wired up so that when the button is pressed, the cart is updated?

Once #87 is merged, there will be an API endpoint that does this, so changing what the button does to calling that endpoint instead should do the trick.
