Add scopes

[rawleyfowler]

Right now you have to apply middleware individually to each route. We should have some sort of scoping/grouping mechanism that injects given middleware into children route declarations.

Here's an idea:

scope: '/location', [ &authorized ], [
    get.assuming('/location', -> $request, $response {
        $response.html('<h1>Hello World!</h1>');
    }),
    post.assuming('/location', -> $request, $response {
        $response.html('<h1>Hello World!</h1>');
    })
];

We can also omit the assuming if we make the routing subroutines return route objects, then just apply the middlewares to the objects.
