Don't let one blocklist, block an other

If a blocklist is blocked by an other and 'pihole -g' is run, update the blocked blocklist by useing an alternate dns server (in this case 1.1.1.1) to acquire the IP adres and download the blocklist using the 'curl --resolve' (https://curl.haxx.se/docs/manpage.html#--resolve)
