Subject: [PATCH 1/3] Update UrlGenerator.php

How to use default named parameters (localize etc).
```
app("url")->setDefaultNamedParameters("locale", app()->getLocale());
```
or
```
app("url")->setDefaultNamedParameters(["locale", app()->getLocale(), "userId" => app("auth")->user()->getKey()]);
```
Just create middleware

```
<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Application;

class UrlGeneratorParameters {

    protected $app;

    public function __construct(Application $app)
    {
        $this->app = $app;
    }

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, \Closure $next)
    {
        $this->app->url->setDefaultNamedParameters("locale", config('app.locale'));

        return $next($request);
    }
}
```
In routes/web.php file
```
app('router')->pattern('locale', '(' . implode('|', config('app.locales')). ')');
app('router')->group(['domain' => '{locale}.telenok.com'], function ()
{
    app("router")->post("some-url", array("as" => "some-name", "uses" => "SomeClass@somemethod"));
});
```

Then instead of
```
<a href="{{  route("some-name") }}">.....</a>
```
you'll get
```
<a href="http://en.telenok.com/some-url">.....</a>
```
