[master][3.0.6] Ebay doesn't work anymore #2645 #2654 

@xillibit  can we move the request to the actual page somehow.  Server should not be trying to fetch this but the individual browser.  If for security reason this is not possible we need to discuss this more.  This is the same problem as the gravatar issue as we could have many ebay items that have to be requested by the server.  Kunena pages that have ebay items and ebay is slow will cause our page to slow down.
