Don't expose `send`

[Raynos]

Having a public send leads to the annoyance of anything that can watch an event can send data.

The way to get around this is to only give access to the send function to the creater of the event.

A way to do so API wise is to change event

function event(callback) {
  var ev = new Event()

  callback(function (data) {
    send(ev, data)
  })

  return ev
}

event(function (next) {
    elem.addEventListener("click", next)
})

That's too complicated, event is supposed to be wrapped in signal to allow only reads.

[Raynos]

Why have both signal and event when event can do it. Reduce complexity by having less layers of bullshit.
