Save style to scene

When the save style to scene checkbox is checked, all settings below inside the border are automatically saved to the active scene upon change.

When the save style to scene checkbox is unchecked the scene will use
the Skalp style settings stored in the model / last used. In other words: you can also use this to copy a style over from another scene by switching back and forth between scenes as doing so will load / activate their style into the model / last used.
