Title: Noted that 'destination' is required.

Jekyll's default destination is "_site", and I'm happy with this, so I don't usually set destination in my _config.yml. If destination isn't set, `rake deploy` will try to rsync /. It's immediately clear what's going on, but I noted this in the README for others to save a step.
