avoid frequent info line redraws in Curses and GTK+ UIs

 * it is now redrawn once after each key press, even if the
   info line has not changed.
 * This is because Interface::update_info() is called very often
   in interactive mode, so it makes more sense to redraw it after user
   interaction (where even unnecessary delays are not noticed so easily),
   than thousands of times in a macro.
 * This is especially important since InterfaceCurses::update_info() now
   also sets the Window title on PDCurses - this is a very costly operation.
 * The same optimization was applied to InterfaceGtk where it is probably
   greatly responsible for the sluggishness of the UI.
   The GTK+ changes are currently UNTESTED.
