`passThrough` to `bindPassThrough`

2.0

Rewrite Hyper

I've been trying to change my Spoons so that the functionality is
functional, and doesn't rely on my particular configuration to operate.
This is a first step towards this.

- overloading `hs.hotkey.modal` instead of having lots of scaffolding to
  pass functions on to the modal.
- `localBindings` -> `passThrough`: made `passThrough` as a function you
  can use wherever.
- rewrite documentation and readme
- included transformation function for anyone still using my v1.0
  configuration.
