On/off layer visibility marks part as changed

[Piotr Gałka]

KiCad 5.1.2 Footprint Editor.
If I on/off visibility of probably any layer (like F.Silks) then footprint is marked as needing to be save.

When I wonted to compare certain aspects of two footprints and because of this I many times switched on and off visibility of some layers each time I wonted to see the other footprint I get a question asking for save previous one.

Layer visibility for PCBs is stored in the .kicad_pcb file but no layer visibility is stored in .kicad_mod files.
