api-v2

To use `2.0.*@dev` version of API... Do the following:

1. Remove old API service providers and just add `Cartalyst\Api\Laravel\ApiServiceProvider` instead.
2. Remove all old API facades (there was overrides for Input, Request etc) and use the following 2 facades:

        'API'         => 'Cartalyst\Api\Laravel\Facades\API',
        'ApiResponse' => 'Cartalyst\Api\Response',

3. Add the following to `app/start.php`, around line 14 (before `$app = new Illuminate\Foundation\Application`:

       require_once __DIR__.'/../vendor/cartalyst/api/src/start.php';

4. Add something like this to your `app/routes.php` file:

```
Route::get('/', function() use ($app)
{
	var_dump(API::get('foo?bar=baz'));

	var_dump(API::post('bar', ['baz' => 'qux', 'fred' => new stdClass]));
});

Route::get('foo', function()
{
	return new ApiResponse(['bar' => 'baz', 'qux' => new stdClass]);
});

Route::post('bar', function()
{
	var_dump(Input::json());
});
```

Give feedback! :)
