KItemViews: Internal directory restructuration

- Move all private headers from the kitemviews-directory into
the 'private' subdirectory.

- Get rid of DolphinDirLister and just use a directory-lister
  internally in KFileItemModel.

- Minor interface-cleanups for signals

-/**
- * @brief Internal helper class for KItemListView to layout the items.
- *
- * The layouter is capable to align the items within a grid. If the
- * scroll-direction is horizontal the column-width of the grid can be
- * variable. If the scroll-direction is vertical the row-height of
- * the grid can be variable.
- *
- * The layouter is implemented in a way that it postpones the expensive
- * layout operation until a property is read the first time after
- * marking the layouter as dirty (see markAsDirty()). This means that
- * changing properties of the layouter is not expensive, only the
- * first read of a property can get expensive.
