Message:

Attach PANELs to all of our WINDOWs

We replace wnoutrefresh with update_panels (except in set cursor; there
we have to guarantee that the window is empty.). The viewwin does not
get a PANEL because it's weird and currently leeches onto someone else's
WINDOW.

Resizing is also rather fiddly because panel wants to know about window
resizes. Not completely sure I got it right yet. The only library I know
of that does something like with with ncurses (libgnt) and they
endwin/refresh to resize the screen.
