TODO:
- Load/Save the view state from/into the stream provided by the ShellBrowser.
- When editing starts on item, set edit text to for editing value.
- Fix shell view to handle view mode popup exec.
- The background context menu should have a pidl just like foreground menus. This
causes crashes when dynamic handlers try to use the NULL pidl.
- Reorder of columns doesn't work - might be bug in comctl32
