Non-published nodes linked to a menu item are not shown in the menu overview page.

Currently, when you link to a published node of which a draft revision is created and saved with workbench moderation, the status column of the menu item mentions "draft". This might be confusing, as there is actually a version of the node currently published. Instead of showing the workbench moderation state, we'd better just show "Published" and "Not published" depending on the node status.

Also, there is a hard dependency on workbench moderation introduced which is not mentioned in the .info file. Solving the previous problem will normally solve this problem as well.

'moderation' should be called differently now as well, maybe 'node_status'?

One last thing: the doc of paddle_menu_manager_tree_check_access() should be modified, to mention it's a variation on menu_tree_check_access() which shows unpublished nodes as well.

Looks good. Waiting for the tests to finish, if those succeed I will merge.

Merged. Thanks!
