Refactored DolphinColumnWidget so that it does not need a hierarchical KDirLister. This simplifies the code a lot and also bypasses the current problems with the KDirLister cache when working on hierarchical directories in parallel. There are some minor regressions which will be fixed, but all in all some improvements are visible already:
- the loading of columns is a lot faster
- preview in columns is working
- no side effects in combination with the treeview-panel because of caching
