Sort Non namespaced packages first

[raygig]

Can you add the ability to sort the Non namespaced packages first Ie:

use stdClass;
use Exception;
use Backend\Dbo\FieldValueDbo;
use Backend\Handler\FieldHandler;
use Backend\Handler\FieldValueOptionHandler;
use Backend\Manager\SystemManager;
use Framework\Arry\Arry;
use Framework\Core\Handler;
use Framework\Core\Model;
use Framework\Util\FileUtil;
use Framework\Util\HtmlUtil;
use Framework\Util\MiscUtil;

stdClass and Exception are in a null namespace which should be sorted first then apply your standard sorting.

The option could be called "Organize Global namespaces first"
