Fix some bugs with a plugin

We use a plugin called "WooCommerce Quickview" to add a quick-view feature in our product listing. For all tests, please use "The Japanese - Snapback". When you click on the chain link on our shop page ([login to view URL]) you will see the quick view window appear... 1) We should see the incremental buttons next to the quantity field, just like on our single product page ([login to view URL]) 2) On the single product page, in the related products section, when you click on the quick-view button, you cannot change the color of the product, clicking on the color swatches doesn't change anything 3) On the home page, there is some CSS issues and the color swatch options are not working as well. This time you can click on them, but the product still doesn't change. Good luck to the bidders! Feel free to ask any questions for clarifications.
