[Freeciv-Dev] (PR#8829) flickering panel nation text

GTK2 client...

Every time the client receives a city packet, the nation name ("Roman") 
on the panel flickers.  This is bad and probably slow.

Looks like the operative function here is gtk_frame_set_text().

If the GTK library can't handle an unchanged text string here without 
flickering, perhaps the client should check to see if the text has 
changed before telling gtk about it.
