- move IShellFolder_fnGetDisplayNameOf() contents into a new function 

SHELL_FS_ProcessDisplayFilename() to call it also in
  ISF_Desktop_fnGetDisplayNameOf() and do the same file system
  processing for the desktop level
- handle hidden file extensions in SHELL_FS_ProcessDisplayFilename(),
  that are configured by "NeverShowExt" in the registry
