Parse scope as rule

[arteymix]

The idea is very simple: empower scope with rule capabilities.

app.scope ("user/<int:id>", (user) => {
    app.get ("posts", (req, res, next, stack) => {
        var id = stack.pop_tail ().get_string ();
    });
});

They should get compiled down to regular expression and then concatenated with the inner representation so that they can be compatible with regex matchers.

It is working with Router.rule.

Now remain the question: do we want that for regular expression as well?
