P2P Blocklist tool

#!/bin/bash
# Filename: blocklists.sh
# Version: 170511
# Author: robz
# AFAIK "transmission" can only be configured to download a single blocklist
# automatically. That default, if set, being the level1 blocklist from
# http://update.transmissionbt.com/level1.gz. This script is to auto download
# the latest or extra P2P blocklists to suppliment or replace the default.
# All being well the script will download from the "$URLS" list and create a
# file which "transmisson-gtk" can parse, the old list will then be replaced
# ready for "transmission-gtk" to create a new binery file on startup.
# If this doesn't happen for some reason the existing will be left in place.
# Script can be used on it's own, or uncomment the last line and create a
# custom launcher for the Transmission bittorent client.
