Initial version for a column view support (thanks a lot to Benjamin Meyer for QColumnView in Qt4.3!). Currently there is a problem when using the DolphinSortFilterProxyModel: some items get duplicated, but I doubt it's an issue in QColumnView (the same issue occurs when using QTreeView) -> further investigations necessary...
