    tdf#157740 FILESAVE PPTX: fix explosion of the number of master slides
    
    - Export correctly the "supported" master slides with the actual slides 
names.
    - Set SlideLayout property at ODF import as well for MasterSlides layout 
type.
    - When we copy a slide with the master slide also copy the SlideLayout 
property
    value as well.
