Ported over to Laravel 4

Hey,

I needed this today as I was sick of adding temp routes so I have quickly ported this over to Laravel 4. 
Have simply added a tag for the Laravel 3 version as I didn't really have time to make it work in both.

To test it out you can following the updated readme, you will also need to add :

    "repositories": [
        {
            	"type": "vcs",
            	"url":  "git://github.com/allmyitjason/laravel-console.git"
        }
    ],
into your composer.json file until the package is submitted to [Packagist](https://packagist.org/).

Enjoy :)
