[NTFS]

Browse source 
Implement support for the FSCTL_GET_NTFS_VOLUME_DATA user request in NtfsUserFsRequest().

This makes NTFSInfo capable of working in ReactOS :-). A picture to show it: http://www.heisspiter.net/~Pierre/rostests/NTFS_info.png
Yes, NTFS Zone isn't computed yet. I'll have a look at it later on.

This doesn't fix nfi.exe though. If it can get its data, it cannot continue. It loops forever on a FSCTL we don't handle yet.
