Summary: use SFSaveDisk and CurDirStore

If you're running MFS, the volume currently being displayed is in the
word at $214 in low memory.  It's called SFSaveDisk in the suppliments.

If you're running HFS, getting the vRefNum is a little more difficult.
SFSaveDisk will contain -(vRefNum of the volume) and CurDirStore, a long
at $398, contains the WDDirid of the folder that's being displayed.  The
WDDirid and vRefNum of the volume can be turned into the vRefNum of the
folder using PBGetWDInfo.

You can force the SF display to start in a given folder by stuffing
SFSaveDisk and CurDirStore before calling the SF routine.
