Details:

The attached changeset is a small patch which will store the STDERR_FILENO
pipe so that it may be restored at exit.  This will allow any errors occurring
at exit to be posted in a terminal if that is where Octave was launched from. 
Otherwise any exit error messages get displayed in the GUI terminal window and
are gone unnoticed along with the closing of the Qt main window.

This isn't necessarily a bug, but in some sense it helps to uncover bugs.  For
example, I was finding a bug at exit that was going unnoticed.  Turns out in
the past couple weeks it was fixed by someone else.  (The _terminal was being
deleted twice.)  Nevertheless, the attached change would have been helpful
from the original onset of the bug.
