Loading wrong config file

Hey,

i'm currently testing your package.

The tasks are working fine, but if I try to run 

   <?= \LbMenu\Menu_Db::forge('menu_slug|or_id')->render(); ?>

In my view, i got always the error message:

```
Fuel\Core\PhpErrorException [ Warning ]:
include(/Applications/MAMP/htdocs/fuel-adminify/fuel/packages/menu/config/menu.php): failed to open stream: No such file or directory
```

I have analysed the problem and after changing the config file in the bootstrap.php
from (Line 28)
```
\Config::load('menu', true);
```

to

```
\Config::load('lbmenu', true);
```

It works fine.
