If an information entry will be added to KFileItemDelegate (like done recently), adjusting the corresponding code in Dolphin is a real pain, as the new information will be shown in Dolphin the following way:

 - 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

To prevent similar painful transitions in future, the class AdditionalInfoManager has been introduced. All parts in Dolphin that access/show/store additional information, use the AdditionalInfoManager now. If a new information entry will be added in KFileItemDelegate in future, only a small adjustment in AdditionalInfoManager will be required.

Still open currently:
- AdditionalInfoDialog does not use AdditionalInfoManager yet
- DolphinView::Sorting should be replaced by KFileItemDelegate::Information, so that the sorting can also be done in a generic way.
- The data for KFileItemDelegate::PathOrUrl is not determined

The open issues will get fixed during the next days.

Kudos to the brave warriors Sebastian and Frank, that tried to add a new information ;-)
