    appDisplay: Add event blocker inhibition API
    
    The event blocker is an actor that is added in between the
    icon grid and the app folder popup in order to guarantee
    that clicking outside the app folder will collapse it.
    
    However, the next patch will require allowing dragging events
    to be passed to folder icons, and the event blocker gets in
    our way here, preventing drag n' drop to work properly.
    
    Add an API to inhibit the event blocker. This API will be
    used by the app folders while an item is dragged.
