I wanted to this for KDE 4.1 already, but well...

Browse source 
Columview refactoring: Get rid of "isColumnView()" special cases in DolphinView and the interface code duplications due to delegating non-QAbstractItemView interfaces to the column view. This reduces the code size + complexity a lot and will make future maintainance of the columnview and DolphinView a lot easier.

Currently there are some regressions in the column view, but this will be fixed during the next 14 days.
