Title: _tree_manager attribute is wrong

In my project I need to implement my own `move_node` method on TreeManager. I created my mptt model MyMpttModel and set `MyMpttModel.objects` to my own MyTreeManager that has its `move_node` implemented.

But I can't really get what I want because admin's TreeEditor._move_node uses model attribute '_tree_manager' that references original TreeManager but not MyTreeManager.

According to documentation `objects` is not a default name for mptt models managers as stated here http://django-mptt.github.com/django-mptt/upgrade.html#treemanager-is-now-the-default-manager-yourmodel-tree-removed
