- fixed a gross bug in SetCurrentDirectoryA (where changing to a new 

non-existent directory would leave the new drive enabled upon aborting
  (fixes CuteFTP install and should fix MANY apps)
  This has probably been caused by myself. *brownpaperbag*
- added GetVolumeInformation serial number bug-for-bug compatibility
- corrected Unicode labels (better CD-ROM handling in general)
- moved CD-ROM label detection code to misc/cdrom.c
- possible to use loopback mounted ISO9660 files
- init some uninitialised drive fields
- remove some unnecessary header includes
