First step to reactivate version control plugin functionality

- Add a DolphinFileItemListWidget that provides icon-overlays
  and colored text for the version state (implementation is
  missing yet)
- Allow KFileItemListWidget to have custom text colors
- Update interface of VersionControlObserver to work with
  KFileItemModel instead of the old model-interface.
