Improved windirs.GetWindowsSpecialDir is ready:

The submitted patch contains the following changes:
1. Added FOLDERID_* constants, required for SHGetKnownFolderPath.
2. Added mapping of legacy CSIDL_* constants to FOLDERID_* constants.
3. Overloaded GetWindowsSpecialDir to work with both CSIDL_* or 
FOLDERID_* constants.
4. Changed GetWindowsSpecialDir to fallback to an alternative API (using 
appropriate remapping of parameters) when the default API function is 
not available.

Existing code that uses GetWindowsSpecialDir(CSIDL_*) should not be 
affected, except for an improved forward compatibility when the 
deprecated SHGetFolderPath is finally removed from Windows API, in which 
case a newer API function will be used automatically.
