    appDisplay: Only allow ctrl-click for apps that can open new windows
    
    Trust the heuristics in shell_app_can_open_new_window() to get it right
    more often than not, and add an appropriate check in activate(). This
    makes the behavior consistent with the dash, e.g. we will try to open
    a new window (and show the corresponding animation) for apps that don't
    have a "New window" item in their dash context menu.
