    Stop returning vector of partitions from Dialog_Rescue_Data class (#759726)
    
    get_partitions() method was returning a vector of partitions.  However
    the calling code only needed to know whether any partitions were found
    or not.  Replace with found_partitions() method reporting the needed
    boolean.
    
    Now use of std::vector<Partition> partitions is hidden within the
    Dialog_Rescue_Data class implementation.
    
    Bug 759726 - Implement Partition object polymorphism
