Give clients the IPV6 address of the DNS server

For IPV6 WAN tracking interfaces, dhcpdv6 does not provide an IPV6
address for the DNS server... fix that.
Rewrite the display_host_results() function to use spaces instead of
tabs. It does a much better job of aligning the fields in each column
and works in all the browsers, particularly chrome which doesn't
support the tab character.

It still isn't perfect due to the javascript alert() function's
use of a proportional font.
Simplify the code.

No need to worry about the second column, we only need to pad the first one.
