[arch-general] archlinux updates error reduction

I commented out mirror.abscission.net in my /etc/pacman.d/mirrorlist since so far as I can tell that server runs too slow and causes yaourt to error out on it persistently. I'm using servers in the United States so this will be of no interest to foreign users of archlinux. jude <jdashiel@shellworld.net> Twitter: @jdashiel
