    Use menus_get_tool_actions() for sensitivity of all  tools at once
    
    Should make the code more maintainable, when we add a new tool.
    The effect on the menu is slightly different than before. Now the
    whole Tools submenu gets disabled, while formerly the single tools
    where insensitive.
