Log:
[SHELL32]
- Add a few helper functions: SH_ParseGuidDisplayName, SHELL32_SetNameOfGuidItem,
SHELL32_GetDetailsOfGuidItem.
- SHELL32_SetNameOfGuidItem is based on a patch for CORE-5995
- Use the helpers in CControlPanelFolder, CDesktopFolder and CDrivesFolder. Implements
getting the comment and renaming registry items in these folders and share some more
code.
