[Coco] curses update

[Willard Goosey]

Now available at http://www.sdc.org/~goosey/os9/curses02.lzh

stdscr is now a WINDOW * (and there was much rejoicing).

There seems to be a problem with getpos() but other than that, the
subset curses seems to work.

It's still very fragile, though.  Too many functions will happily
dereference a NULL pointer.

I'm going to try to update this daily, so download it, break it, fix
it, and send me the fixes! :-)
