Problem: How can JavaScript code be added to the HC Control panel?

Solution: Customers can add their own javascript code to run on HC pages by putting the whole script inside <script> ... </script> tag in the file 'App.config' as shown below. App.config file can be found at HC10 installation path: X:\Program Files\Hosting Controller\Portal\app.config
