Although it should be possible using the menu item's palette (see
QWidget::palette() and QWidget::setPalette()) I consider this a bad idea
concerning usability:

- Why should a user assume that there _is_ an action behind a menu item that
looks disabled?
- Why is the user forced to use the complicated way to enable the action?
The action could be even self-enabling on the first click of the menu item.
- If the user can enable the action, why not enable it by default?
