Binary-only Quake3 packages

[Joerg Sonnenberger <joerg%britannica.bec.de@localhost>]

Hi all,
is there a good reason for keeping the games/quake3*? The distfiles are
gone again and there are questions on the redistribution rights anyway.
games/ioquake3 is based on the GPL release from id software and doesn't
have most of the attached problems.
