Improvements

- The path of the cookie indicating the visitor's acceptance/rejection of cookies is being set to "/" now. This ensures that only one such cookie will be created. Before, the path was not being set explicitly and it would vary, depending on the URL of the page. This way the created cookie would not be detected sometimes, the cookie warning would show up again and a second cookie would be created.

- The current page is now being refreshed, whenever the user chooses to accept or reject cookies, so that the effects of the activation of the various widgets is immediate, if cookies have been accepted.
