"""Shipped skin defaults of skin.milionar: Home menu, skin switches, Home widgets and their context menus.

resources/defaults/skin.json is a snapshot of the maintainer's skin settings (scripts/snapshot_defaults.py). The skin
Home `<onload>` runs the `skin_defaults` action once for every install whose skin settings do not carry FLAG yet,
so everybody who updates gets these defaults once; slots.write_defaults ("Obnovit výchozí widgety") uses them too.
To force the defaults again in a later release, raise the flag name here and in Home.xml (MilionarDefaultsV9 -> V10).
