Remove references to non-gpl artwork license
The non-gpl warnings in WPrefs.app/tiff/README
and WPrefs.app/README were misleading, because
they were refering to Marco van Hylckama Vlieg's
work which was licensed with OpenContent License.
But as Alfredo Kojima wrote in the Changelog in
commit
f65c5498143ece819010b6 from 30.03.2010,
Marco's icons were licensed with the GPL.
Furthermore, in an email to wmaker-dev on 10.03.2010,
Marco confirmed:
"Anyway, I have no problem with the artwork being
licensed under GPL or whatsoever."
