Automatically reflect node access

If a menu item points to a node controlled by Taxonomy Access Control, it would make sense for the menu to just reflect that node's permissions as already assigned by TAC. It is unlikely that one would ever need to assign different permissions to the menu item:

• If the menu item allowed more roles than the node to which it points, then some users would get access denied errors.
• If the menu item had fewer roles than the node to which it points, then you would be practicing security by obscurity, which is not true security.

Right now I am making double effort by modifying access permissions on the node and on the menu item. Not only does this take more time, it is more error prone because it could allow either of the above problems to occur.
