Add KU Leuven listserv muter

The KU Leuven mailing list are regenerated every day. So in order to
prevent anoying mails from reaching our already quite full mailboxes, we
can just mute te list periodically.

listunserv.sh

+#!/bin/sh
+LIST="KULSTUD"
+LOGIN_TOKEN=""
+LOGIN_USER="voornaam.achternaam@student.kuleuven.be"
+REALNAME="Voornaam+Achternaam"
+
+for item in $LIST
+do
+   echo $item
+   curl -d @- -X POST https://ls.kuleuven.be/cgi-bin/wa <<< "SUBED2=${item}&X=${LOGIN_TOKEN}&Y=${LOGIN_USER}&_charset_=UTF-8&L=${item}&p=${REALNAME}&q=${REALNAME}&s=${LOGIN_USER}&t=${LOGIN_USER}&0=&1=&2=&3=NOMAIL&4="
