title: Show label "Low in stock" for configurable products
body: <p>Hello guys the version that i`m using is Magento 1.7.0.2,</p>
  
  <p>I want to create a label for the configurable products, that will appear when the total quantity will be under 5. The label will be "Low in stock" and will appear on the category page on the image just like in this example.</p>
  
  <p>Right now i am using extension EM Product Labels, but this works only on simple products, because the simple product has just 1 type of quantity in stock.</p>
  
  <p>You can find example on this link :</p>
