Freeciv lacks any sort of Icon in it's menu entries, except for the gnome globe (if you are a gnome user that is). It is also categorised incorrectly. The below patches are against freeciv-2.0.7 and freeciv-2.0.8 ebuilds, the icon is also included. The patches make the ebuild modify the .desktop file included with freeciv so that it uses this icon and it modifies the categories line as well.

Oh and also, the icon was obtained from the following URL: http://bugs.freeciv.org/Ticket/Display.html?id=13508
Now in portage. Thanks for report and time
