Allow curly braces in Laravel URL::route() parameters array

URL.php

<?php namespace Cego\Facades;

class URL extends \Illuminate\Support\Facades\URL
{
    public static function route($name, $parameters = array(), $absolute = true, $route = null)
    {
        $urlGenerator = static::$app['url'];
        /* @var \Illuminate\Routing\UrlGenerator $urlGenerator */
        $route = $urlGenerator->route($name, $parameters, $absolute, $route);

        //untranslate the { and } characters.
        return str_replace(['%7B','%7D'],['{','}'],$route);
    }
}

This is absolutely needed in core.
