[issue1329] Make ip-screen display each IP only once

[Andras Korn]

New submission from Andras Korn <korn-grml at elan.rulez.org>:

If the same IP is present on more than one interface, ip-screen will list it
several times, e.g.

# ip-screen 
169.254.255.254 | 169.254.0.1 | 169.254.255.254 | 169.254.0.1 | 169.254.0.1 |
169.254.15.254

This takes up precious space in the status line.

It would also be nice to be able to exclude IPs from being printed at all
(individually or by subnet), for example by way of an environment variable or
command line option.
