settings.yml: use_default_settings.categories_as_tabs

Update commit ab130786ab

With use_default_settings,
* categories_as_tabs add new categories
* use_default_settings.categories_as_tabs.remove removes categories
* use_default_settings.categories_as_tabs.keep_only keeps only the refernce categories

This is going to allow to keep the icon definition (see #690 )
