* - As additional columns in the details view
* - As additional lines in the icons view
* - As menu entries in the "Sort By" and "Additional Information" groups
* - As popup menu entries in the details view header popup
* - As checkable entries in the View Properties dialog
*
* The AdditionalInfoAccessor provides a central place to get all available keys,
* the corresponding translations, action names, etc., so that modifications or
* extensions in KFileItemDelegate only require adjustments in the implementation
* of this class.
