Use zsh for main Moabian shell

If you spend a lot of time on the Pi, you're going to want zsh as your main shell instead of the default bash. You can use my Dotfiles-viM-Zsh config here:

cd
git clone https://github.com/scottstanfield/dmz
dmz/os/raspian.sh
dmz/install.sh
chsh -s $(which zsh)

# log out, then back in
