@Re-introduce webmin. Thanks to Dell'Aica Valentino and PhobosK for the ebuilds. This fixes bug #348432

(Portage version: 2.2.0_alpha55/cvs/Linux x86_64)

# gentoo-setup.sh
# A modified original Webmin setup.sh script to comply with Gentoo specifics
#
# Modification done by: PhobosK <phobosk@@kbfx.net>
#
# This script runs after the webmin archive is installed, and in the pkg_config() phase.
# It does setup the various config files of Webmin depending on if it is
# a new install, an upgrade or a reset.
