Subject: [PATCH] Ensure Prezto submodule is initialized on clone/install

install.sh: use --recurse-submodules on the initial clone, and always
run 'git submodule update --init --recursive' before rake install so a
fresh checkout doesn't leave zsh/prezto empty.

README: document --recurse-submodules for manual clones; mention the
recovery command for existing shallow clones.

Fixes: bad math expression errors and 'no such file or directory:
~/.zprezto/runcoms/zshrc' on fresh shell startup when the Prezto
submodule hadn't been initialized.
