Don't retry get_window_title

Browse Source 
Call get_window_title() at most once per terminal, even if it fails.
If ELinks is configured with X11 support, get_window_title() calls
XOpenDisplay(), which can sleep if $DISPLAY does not respond.
This delay was previously incurred every time ELinks changed the
title.  Besides, if ELinks had already changed the title, setting
ditrm->orig_title = get_window_title(); did not make sense anyway.
