eiskaltdc extra licence

[Andrey Tataranovich <tataranovich@gmail.com>]

Hi all, 

I working on packaging eiskaltdc - direct connect client (see #540458).
This program have extra licence information (you can see it on 
http://rootshell.be/~ice/tmp/COPYING) wich installed by default in
/usr/share/eiskaltdc/COPYING. This produced lintian warning
(W: eiskaltdc: extra-license-file usr/share/eiskaltdc/COPYING).

This file is used in About/Licence dialog.

What should I do to satisfy DEBIAN policy?

a) rename/move this file another place and patch code
b) add lintian override

Thanks in advance.
