Subject: LinGui: work around yet another gtk+-3 bug GtkTextView gets confused
 if you try to set it's contents again while in a callback for a change to the
 TextView.  So prevent such behavior by the app.  Requires updating the
 x264Option TextView in the background (idle loop) rather than immediately.
