When a user selects an RSS-feed , a function called "showResult()" is executed. The function is triggered by the "onchange" event
The showResult() function does the following:
  * Check if an RSS-feed is selected
  * Create an XMLHttpRequest object
  * Create the function to be executed when the server response is ready
  * Send the request off to a file on the server
  * Notice that a parameter (q) is added to the URL (with the content of the dropdown list)
