dolphin/src/treeviewsidebarpage.h
Rafael Fernández López c8072005fa Create the new architecture for KCategorizedView. Now DolphinModel is created, inheriting KDirModel for returning valid data for the role of the category of
an item. DolphinSortFilterProxyModel implements now methods lessThanCategoryMethod and lessThanGeneralMethod from KCategorizedSortFilterProxyModel.

The only thing that needs to be adapted is the keyboard navigation on the KCategorizedView.
