DOS ain't dead

I posted a new version of NetDrive a few days ago. The big change is that the server side now has a journaling feature for drive images, allowing you to mark a checkpoint in the journal and then later undo changes you made by "unrolling" back to the checkpoint. It's basically a drive level "undo" feature that works in milliseconds, and you can control it all from the DOS command line.

Other changes include more robust error handling and retries on both the client side and the server side. I also fixed a small glitch that affected FreeDOS when it tried to read the placeholder RAM disk that is used when no remote image is connected. (The driver properly shows the placeholder file in the RAM disk now.)

The device driver is still tiny (less than 6KB of RAM), and DOS 2.1 upward are supported.
