Provide closure filters $route and $request vars

When adding filters in Controller constructs, provide closure filters $route and $request variables besides $parameters array.

````php
// in construct
$this->beforeFilter(function($route, $request, $parameters)
{
 // code
}
````

One difference, now when calling afterFilter, it'll provide $response as the third parameter:

````php
// in construct
$this->afterFilter(function($route, $request, $response)
{
 // code
}
````
