Log:
[SHELL32] Shell extension support for files.
- CFSFolder: Implement binding to files, implement loading arbitrary extensions for
GetUIObjectOf from the registry, implement loading IconHandler shell extensions. Use the
new helper routines to simplify getting the drop target.
- Improve the shortcut icons hack.
