add IPv6 support in the hosts file

Browse source 
Still need to get lighted to use IPv6.  I am doing this because some
ads can get through using IPv6 if the IPv4 version is blocked.  Also,
it seems to work fine as far as performance even though it doubles the
file size...

Also added a few comments for better documentation.
