[arch-general] Add wpa_supplicant to the Group 'Base'

Hi I recently installed archlinux over the air (wifi) and after a reboot I realizied sh**t you forgot to install wpa_supplicant to get connect to the world (over wifi / wpa/wpa2) and install more packages. So I had to restart, boot to the live system, mount the whole crypt stuff, (arch-chroot) and install wpa_supplicant. In my opinion wpa_supplicant is an important tool, so is it possible to add it to the group 'base'? Cheers H8H
