Add Ubuntu instructions to `mehserve install` about mehserve

[benjie]

• sudo for everything

[benjie]

Actually, for loopback support we need:

iptables -t nat -A OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 12439

[benjie]

service dnsmasq restart

[benjie]

sudo iptables-save

[benjie]

Just use 127.0.0.1 otherwise things that bind specifically to that host will fail to receive the network requests.

(For historical reference, issue description was originally

sudo apt-get install dnsmasq
echo > /etc/dnsmasq.d/dev-tld <<<HERE
local=/dev/
address=/dev/127.0.0.5
HERE
iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 12439 -j ACCEPT
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 12439

)
