[PATCH 3/5] info.c: add a method to clear all GtkListStore allocations

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

Add a new method in info.c called info_widget_destroy(), which
clears all GtkListStore instances. The method is exposed via
display-gtk.h and called from gtk-gui.c:on_destroy().
