Title: Implement list -1

I would like to use list option with `-1` like the brew command.

```bash
$ brew list -1
ack
autoconf
...

$ brew list
ack	go	libpng	mysql	rbenv-default-gems
autoconf	groonga	libtool	openssl	readline
...
```

How about this?
```bash
$ brew cask list -1
alfred
android-studio
appcleaner
vagrant
virtualbox

$ brew cask list
alfred	android-studio	appcleaner	vagrant	virtualbox
