Subject: [PATCH 2/3] trigger events on update

Dispatch the custom events on `Ps.update`:

```
container.scrollTop = 50;
Ps.update(container);
```

This is useful for controlling the scroll position via left/right
arrows and enabling/disabling these arrows on scroll or when the
start/end is reached. This also allows for the events to be dispatched
on page load by calling `Ps.update` right after `Ps.initialise`.
