Remove remaining uses of request superglobals

I went through the application and removed any remaining uses of request superglobals ($_GET, $_POST, $_REQUEST) and replaced them with the relevant Symfony Request API call. The only uses of request superglobals that remain that I could find are those in utility classes not specific to Bolt.
