Remove window(1) from the base system.

Some time ago Tom Rhodes sent me an email that he was willing to perform
various cleanups to the window(1) source code. After some discussion, we
both decided the best thing to do, was to move window(1) to the ports
tree. The application isn't used a lot nowadays, mainly because it has
been superseeded by screen, tmux, etc.

A couple of hours ago Tom committed window(1) to ports (misc/window), so
I'm removing it from the tree. I don't think people will really miss it,
but I'm describing the change in UPDATING anyway.
