Drop support for ZSH

I've been using Fish consistently for about a month now, and I don't see myself
switching back to ZSH. Some of the code from this commit should be published. I
may get around to that one day. Before I did that, I would need to clean it up
and document it, which I won't be doing today.

Thank you, ZSH, for your service.
