issue an error message if the browser doesn't have JavaScript

SS requires JavaScript to be present. If the user wants to use web-blast on a non-JS browser, I am sure there are other alternatives out there. If someone wants to send a pull request to make SS work again on a non-JS browser, I am keen to discuss the options. Signed-off-by: Anurag Priyam <anurag08priyam@gmail.com>
