Open Sourcing DOS 4

@shanselman
Imagine the possibilities.

An operating system usable by virtually every still-functioning computer in existance today, and a horde of programmers who can work in such a simplified environment that can write virtually any program for any task needed.

Who can write me a DOS 4 web server?

@dec_hl I think
@starraven is looking for you...

@shanselman

@blackcoffeerider @starraven @shanselman well, I never figured out what is wrong with my quick'n'dirty HTTPS-DOS webserver. But the HTTP-Server I wrote for DOjS is working OK šŸ˜‚

Update: I figured it out and got it working! IPv6 support did try to enable multicast and the packet driver did not like that!
I'll put together a binary release now.
