ACL inconsistencies

Hi,

We are using another extension for surveys but are re-evaluating our options.

We are testing the vquiz extension to compare and here are a few things we have noticed.

ACL management
We use group with access rights for our teams in our backend and wanted to create a group specially to manage surveys. Let's call it survey support (see attachment for rights).

In this case the menu on the left shows the right choices but the top menu of the admin shows all the choices so it looks like the top menu items are not tested.

When we access the quizzes, the quizzes are well displayed but there is an error message on top of the list saying:
Notice: Undefined property: stdClass::$checked_out in
administrator/components/com_vquiz/views/quizmanager/tmpl/default.php on line 247

To avoid having this message, you have to enable the com_checkin components for this group so I think there is a test missing in default.php to avoid using the $checked_out if the user doesn't have access to the feature.

Besides that. Good job on the extension.
