Zeronet via docker

If you have docker installed already (including docker-compose), running zeronet could be as easy as this (thanks to @tezos-blue on Matrix/Riot).

wget https://raw.githubusercontent.com/tezos/tezos/master/scripts/alphanet.sh
mv alphanet.sh zeronet.sh
chmod +x zeronet.sh
./zeronet.sh start

Note that the script (alphanet.sh, renamed to zeronet.sh) checks to see what name it is run as and brings up the appropriate docker image -- alphanet or zeronet -- automatically.

The various commands documented for alphanet.sh work much the same for zeronet.sh, except for where the underlying tezos client commands have changed since the latest alphanet code.
