Add support for mapping route params to regexps for processing

It's desirable to both use string-based routes with named params, e.g.,
`"/posts/:id"`, and assign some processing to route param values, e.g.,
`id` should be a number.

This adds a feature to Router to support mapping named params to regular
expressions. See the following example:

    var router = new Y.Router({
        params: {id: /^\d+$/}
    });

    router.route('/posts/:id', function (req) {
        // This route will only be executed when `id` is a number.
        // `req.params.id` is the result object/captures array from
        // `exec()`-ing the regular expression.
        Y.log('Show post: ' req.params.id[0]);
    });

    router.save('/posts/1'); // => "Show post: 1"

    // This won't log anything because `id` is not a number.
    router.save('/posts/asdf');
Add support for also mapping route params to functions for processing

Now both regexps and functions are supported for route param formatting
and validation.
