    Reworked copying of PresetBundles:
    1) Simplified by using the default copy constructors and copy operators.
    2) Made safer by not allowing PresetCollection and PhysicalPrinterPresetCollection
       to be copied or instantiated outside of PresetBundle.
    3) Fixed Preset::vendor pointers after copying PresetBundle.
