Add variables in routes with view

Add the ability to pass simple variables in the route for views. Sometimes we derive a route from a template where we want to pass a title or fixed variable, but it's not possible.

An example of how this would be used:

PHP Code:

$routes->view('/', 'login', ['title' => 'Login', 'message' => 'Welcome to login']);

$routes->view('change-password', 'change-pass', ['title' => 'Change Password']);
