SW: Drop firmware-ipw2x00 which has been integrated in last commit ("Spring cleaning") from GRML_MEDIUM + GRML_FULL.

Automated installation fails with:

| Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.30_all.deb) ...
|
| firmware-ipw2x00 agree question could not be asked
| try 'dpkg-reconfigure debconf' to select a frontend other than noninteractive
|
| dpkg: error processing /var/cache/apt/archives/firmware-ipw2x00_0.30_all.deb (--unpack):
|  subprocess new pre-installation script returned error exit status 2

So first of all we'd have to check out
http://packages.debian.org/changelogs/pool/non-free/f/firmware-nonfree/current/firmware-ipw2x00.copyright
in detail and if firmware-ipw2x00 is really distributable for
Grml we'd have to provide according debconf preseeding so
automated installation works.
